Perhaps the greatest effect of drug abuse lies in the various adverse changes that it gives to the brain, and this can affect the way the individual thinks and acts within social situations. The behavioral changes attributed to drug use can vary according to the type of drugs taken.
So, what are the things that you need to watch out for if you think that your friend or loved one is using drugs?
STIMULANTS
If the individual used stimulants such as cocaine and meth, he may experience an episode of restlessness since stimulants give an artificial feeling of “being energized”. This restlessness can manifest itself through being overly cheerful, talkative, and being too excited over even the smallest of things.
DEPRESSANTS
Depressants such as marijuana have the opposite effect on the body, and the user may become more lethargic when he is high. If the individual shows signs of being too placid, or if his responsiveness and attention span wanes, chances are that he may be taking depressants. Depression is also another side-effect of this type of drug, and the individual can also show signs of voluntary self-isolation because of it.
HALLUCINOGENS
Hallucinogens have the most unusual effect on the body, since it allows the user to experience hallucinations. If taken in high doses, the drug can cause a feeling of hallucinating that may persist even long after the user has taken it, and this can compromise his relationships with the people around him. The user can also show signs of preferring to be in his make-believe world rather than deal with reality itself.
While drugs may have a general effect on the body, the behavioral changes can vary according to the type of drug taken. Stimulants, depressants, and hallucinogens may each have their corresponding consequences, but this does not make any less dangerous than the other.
