Top 5 Most Dangerous Drugs To Use
I want to first thank The Lancet for this information. I probably would have placed certain substances in different places but I will go with this. This list contains information on the top 5 most dangerous drugs to use based on their: 1.) Physical harm to the user, 2.) Addiction possibility, 3.) How the drug affects those around the user.
Ranked from the least to most dangerous, the five most dangerous substances are:
5. Alcohol (Depressant that slows the function of the central nervous system)
Slang Terms: Booze, Brews, Hard Stuff, Red-Eye, Hooch, Juice
Now, a lot of people will probably laugh at where alcohol is placed in this list, or the fact that it’s even on this list to begin with, but it’s true that alcohol is a dangerous substance and it’s important to know about it. The legal drinking age in the United States is 21. In other countries it is lower, even significantly lower. Every day there are millions of people in the USA who enjoy alcoholic beverages responsibly, but there are plenty of abusers out there and a percentage of them are people under the age of 21.
Alcohol is naturally known as “the most abused social drug,” but that’s simply because it’s legal to purchase and easy to obtain. Alcohol depresses the CNS (Central Nervous System). This affects how a person acts and alters a person’s state of mind. Alcohol simply changes a person which in term will turn a person into someone they’re not. Innocent people can get hurt, as well as the person who is intoxicated.
According to the National Center on Addiction and Substance Abuse, almost 80% of high school students have tried alcohol, which is a very high number. It has also been officially stated that alcohol is used more frequently than all other illicit drugs combined. Last, 30% of high school seniors and 25% of tenth graders reported that they have binge drank (drinking large amounts of alcohol in a short period of time) before.
Chronic users of alcohol that suddenly stop will have to go through withdrawal. Alcohol withdrawal is accompanied by a group of symptoms that are uncomfortable and possibly life-threatening. Not all people will suffer though alcohol withdrawal, but most people who drink large portions of alcohol for a long time will. There are mild, moderate, and severe symptoms of withdrawal that range from anxiety and depression to agitation and convulsions. It’s important to seek medical help if coming off alcohol is hard.
4. Street Methadone (Synthetic opioid, used medically as an analgesic, antitussive and a maintenance anti-addictive for patients interested in coming off of other opioids)
Slang Terms: Amidone, Chocolate Chip Cookies, Fizzies, Wafer
Street methadone is medical methadone that is sold or given to someone it was not prescribed for. It’s also cut or diluted so that drug dealers can make more money, but it also makes the methadone more dangerous- which leads the person using the drug to a possible overdose. Methadone is a synthetic (man-made) narcotic that is usually used to treat narcotic addiction, as well as to act as a pain killer for severe pain.
Street methadone is a very slow-acting drug, which is why it’s very dangerous. It can take hours before a person receives the full effects of methadone, and it lasts more than 24 hours. The thing with methadone is even though it produces a calming euphoria (feeling high), it does not provide a “rush” like heroin does, so people looking for that intense rush will only hurt themselves by overdosing.
Once users are dependent on methadone, the consequences aren’t pleasant. Chronic users will experience withdrawal symptoms that include, but are not limited to: muscle tremors, nausea, vomiting, stomach pains, diarrhea, etc. Since methadone has a fairly long half-life of 24-36 hours, it will take a while before the withdrawal sets it, which is also another dangerous fact of why this drug is bad news.
3. Barbiturates (Drugs that act as central nervous system depressants, and produce effects such as mild sedation and anesthesia)
Slang Terms: Barbs, Yellow Jackets, Goof Balls, Reds, Blues, Christmas Trees, Amy’s, Rainbows
Barbiturates were first used medically in the early 1900s. They are prescription sedatives- depressants that slow the central nervous system down, and there are more than 2,500 known synthetic barbiturates. When barbiturates were popular, there were only about 50 of them that were used for medical purposes, however other purposes were what lead to why they are not prescribed as much anymore. There are also other drugs that provide similar effects, and aren’t as addicting.
It’s true that barbiturates can be closely compared to alcohol, and many people do refer to them as “alcohol in pill form,” and they can also be injected. People who do not want to drink alcohol usually take barbiturates to receive the euphoria (feeling high) and relaxation that it provides. Many people hunt for barbiturates on the streets because many doctors just won’t prescribe them, and it’s very illegal to take them if they are not prescribed to you. On the street, barbiturates are often used in combination with cocaine, amphetamines, and crystal meth to enhance the high.
Barbiturate tolerance develops very quickly, which means that a higher dose is needed to receive the same feeling as before, which increases the danger of an overdose. If a user overdoses or takes the medication with alcohol, death is possible due to excessive depression of the respiratory center in the brain. Long-term users will also suffer through withdrawal that is similar to other opioids, and is also uncomfortable. Some of the symptoms of barbiturate withdrawal include tremors, sweating, anxiety, irritability, nausea, vomiting, seizures, etc.
2. Cocaine (Potent stimulant that directly affects the brain)
Street Terms: Powder: Blunt, Blow, Candy, Coca, Coke; Smokeable: Crack, Rock, Chalk, Freebase, Love
Cocaine is the most potent stimulant that is also considered to be one of the greatest drug threats to the world due to its violence associated with trafficking and the physical and psychological effects associated with its use. Cocaine is one of the oldest known drugs and coca leaves (Erythroxylon coca), the source of cocaine, have been ingested for thousands of years. Most cocaine in the USA is snorted, which produces effects including euphoria (feeling high), relaxation, and an increased sense of well-being, although the effects disappear quickly which leaves the user craving more.
Since users crave more of the drug, that leads to more money being spent- so not only is the user getting hooked, they are also throwing a lot of money towards the dealer. Cocaine can either be snorted, injected, or smoked. Snorting cocaine is the slowest route of administration, but lasts the longest. Smoking cocaine allows extremely high doses of the drug to reach the brain very quickly, which produces an intense and immediate high. The most intense high comes from injection, which allows the drug to enter the bloodstream immediately. Upon injection, the cocaine reaches the brain within a couple of seconds, and the intense rush can induce some users to vomit uncontrollably. While the method of injection provides such an intense rush, this increases the risk of acquiring the AIDs virus, especially if needles are shared.
What makes this drug so dangerous is the fact that it’s so addicting. People will tell themselves that they will only try it once, but after they have tried it the first time, the next will happen very soon. Whichever way the drug is administered will result in an intense euphoria, so getting away from cocaine is not easy. Long-term users will most likely suffer from withdrawal symptoms, but they aren’t as uncomfortable as other drugs. Primary symptoms may include depression, fatigue, unpleasant dreams, agitation, restless behavior, intense cravings for the drug, etc.
1. Heroin (Highly addictive semi-synthetic opioid derived from morphine)
Slang Terms: Junk, Dope, Big H, Horse, Smack, Brown Sugar, Dust
At the number 1 spot, heroin. Heroin was first synthesized from morphine back in 1874. It’s amazing that heroin used to be legal back in the early 1900s, but due to the “major social problem” that was caused, as well as its potential for abuse- heroin is now illegal and is the most dangerous drug to use. As with other opiates, heroin is used for its ability to relieve severe pain, but it is also used recreationally. Heroin provides an intense high that many people consider to be godlike. Once the user gets hooked, it can be very hard to come off of heroin.
Heroin can be used in a variety of different ways, depending on the purity of the drug and the user’s preference. Heroin can either be injected, smoked, or snorted, but there are many different alternatives to the three main ways heroin is administered. Users tend to mix heroin with marijuana, smoke it in a water pipe or standard pipe, inhale it as smoke through a straw (known as “chasing the dragon”), or snort it as powder.
Heroin’s “godlike” effects include intense euphoria (feeling high), relaxation, warm flushing of the skin, and an increased sense of well-being. Following the intense euphoria, users tend to nod off (known as “going on the nod,” which is an alternately wakeful and drowsy state), which many people state as being very relaxing. Long-term users of heroin will suffer through very uncomfortable withdrawal that many users cannot go through without medical assistance. Withdrawal symptoms may occur as early as a few hours after the last dose, since heroin’s half-life is short. Some of the symptoms include but are not limited to: extreme drug craving, muscle/bone pain, restlessness, insomnia, diarrhea, vomiting, cold flashes w/ goosebumps (”cold-turkey”), kicking movements (”kicking the habit”), etc.
As stated before, the symptoms of heroin withdrawal can be very uncomfortable, and users who quit abruptly (cold turkey) most likely will not be able to go through it without seeking medical help. Major withdrawal symptoms tend to peak between 48-72 hours and subside after about a week. Users of prescription opiates taper down to lower doses of the pain-killer before coming off of the drug, and with heroin this is done through a drug rehab program, although another drug is given to the person. Please seek medical attention if you or someone you know has a heroin addiction.
