All drugs are ; heroins the worst though!
Depends on the person taking them.
The addictive substance
Rohypnol is the benzodiazepine flunitrazepam. Because of the addictive potential of these drugs, it would be classified as a hard drug.
The most addictive drugs are inhaled drugs such as tobacco (nicotine) and crack cocaine, as well as injected drugs such as heroin. Powerful stimulants, such as methamphetamine, are also highly addictive.
It could. It depends on the person. Some people have addictive personalities -- they can't do any drug without getting addicted to it. Others have this addictive personality to a certain extent, and tend to drink or do drugs to excess, but are able to keep themselves from becoming full-blown addicts. And others do not have this addictive personality at all, and are able to do drugs, even hard drugs like cocaine or heroin, only a little bit, once in awhile.
Marijuana is not addictive in the way that other drugs are. Instead it is psychologically addicting. Which means that your brain thinks you need it when you don't. The only time it is physically addictive is when it is laced with other drugs
cocaine, crack, heroin ,ecstasy, alcohol. There are others, but these are def. at the top for addictive drugs
Codeine is the classic structural formula for all addictive drugs.
boner
Vicodin is a drug of the opiate class, one of the most addictive groups of drugs.
Caffeine is considered to be mildly addictive compared to drugs. It can lead to physical dependence and withdrawal symptoms, but the addiction potential is generally lower than that of many drugs.
Hard drugs are typically more potent and addictive substances that have a higher potential for abuse and dependency, such as heroin and cocaine. Soft drugs, on the other hand, are usually less potent and less addictive, like marijuana and prescription painkillers. Hard drugs are more strictly regulated and are associated with more severe legal and health consequences compared to soft drugs.
