Top Most Addictive Illegal Drugs

Do you know how the drug that is addictive is you are currently taking? While many factors determine whether or not you will become hooked on drugs, the risks related to becoming addicted to your drugs is greater than others. The reason? While others may take to get addicted to — a few drugs may have you hooked after just the first try — drugs have varying degrees of addictiveness.


Heroin’s capacity to quickly penetrate the brain results in the surge of intense euphoria or the “rush”, the heroin addicts face.

Additionally, heroin affects your brain’s nervous system. It tricks the brain into pausing the production of high feelings so that the consumer can experience no feelings without the assistance of the drug. This is why heroin users experience drug cravings when the drug is stopped.

Crack Cocaine:

Hunting as stones, it is heated and smoked through a glass hand pipe.

Similar to heroin, the crack cocaine also activates the central nervous system and begins making excessive amounts of dopamine, the neurotransmitter responsible for feelings of pleasure, to be released.

Smoking crack allows it to reach the brain faster than if it were snorted, resulting in an intense and immediate “high” that lasts around 15 minutes. Since the effects are so short-lived, users frequently smoke it to maintain. It is not unusual for someone to become addicted to it after their first time.


Just because smoking is legal does not mean we should ignore the addictive effects of nicotine. According to the National Institute on Drug Abuse, nearly 35 million smokers want to quit annually, but over 85 percent of people who attempt to quit on their relapse– many per week.

A fraction of this abusive nature of nicotine derives from nicotine’s ability to stimulate the nervous pathway by increasing amounts of dopamine. Nicotine mimics another compound in mind–the receptors. Normal smoking requires the user maintain consuming nicotine to maintain normal brain functioning and lowers the number and sensitivity of these receptors.


It is an opium-based medicinal drug commonly used to deal with heroin or morphine dependence, in a clinical setting, tolerance to this drug is considered beneficial. As the risk for Methadone addiction is low (less than 1%) when taken as prescribed and under medical supervision, people using this medicine recreationally can become dependent on it. The effects of methadone are quite similar to the outcomes of heroin, but withdrawal from methadone is painful and severe, often lasting more than a month.


It simulates none the two major compounds in the brain: dopamine and norepinephrine, the neurotransmitter responsible for feelings of alertness and energy (adrenaline).

Meth can discharge as much as ten times the standard level of dopamine, and also the excess of artificial norepinephrine inhibits organic adrenaline production–mainly messing up the chemical balance in the brain. Worse, methamphetamine can harm the dopamine and neurons, causing a drop in their output.

You guessed it: Tolerance, cravings, and taking meth.


Alcohol influences two Major chemicals in the brain that triggers addiction:

Dopamine: Like the others, alcohol triggers the nervous system and produces feelings of satisfaction and pleasure.

Endorphins: Endorphins are the brain’s natural painkiller, and recent research is revealing how increased levels of endorphins may increase the pleasurable effects of alcohol, especially in heavy drinkers.

Alcohol withdrawal can also be among the worst of all drug withdrawals, so acute it could cause death.


Actually, all of the Cocaine withdrawal symptoms are not the same as seen in alcohol dependence, but cocaine functions in precisely the same way: it contrasts with the amount of dopamine in the brain and causes intense cravings. Snorting cocaine is much behind although smoking crack is the quickest way to get cocaine into your blood vessels. Powder cocaine has a short rapid and high tolerance.


Though amphetamines aren’t as addictive as meth, it still acts on precisely the same nervous circuit. Amphetamines give an array of effects: weight loss, assurance, euphoria, energy, and feelings of self-accomplishment besides inducing rapid endurance and extreme cravings. Abusers of Adderall and Ritalin find it hard to stop, but they don’t even wish to leave.


Benzodiazepines such as Valium, Xanax, and Klonopin increases the effectiveness of GABA, the brain’s “nerve calming” agent.  And, as usual, the body attempts to compensate for the increase of GABA by lowering the sensitivity of GABA receptor tissues. As the body continues to accommodate, tolerance builds fast and quitting gets harder when tolerance is high.

How Drugs Mess with Dopamine:

Dopamine is the medication that produces the feeling of satisfaction and well-being. By attaching to dopamine receptors, dopamine enters neurons. When levels of dopamine increase, your body attempts to balance out the extra dopamine. Hence, when a folk stops consuming the drug, dopamine levels drop immensely, which is the drug is craved by the individual so much. After all, your body needs its dopamine.
