ANSWER: MARIJUANA
EXPLANATION: Marijuana is an psychoactive drug gotten from cannabis plant (including dried leaves, flowers, stems, and seeds). The source plants include Cannabis sativa, Cannabis indica, and Cannabis ruderalis.
However, tetrahydrocannabinol (THC) is the main psychoactive component in the cannabis plant. They are primarily used for medical or recreational reasons.
Marijuana causes both physical and mental changes. When administered it causes concentration difficulty, impaired short-term memory, impaired body movement, increase in appetite (munchies) plus the amotivational syndrome and etc.
Lastly, Marijuana legalization differs from states to state. Most states that do legalized it, are often for medical purposes and also placed restrictions on handling by individuals. Some states banned the use of marijuana, presumably because of the adverse effects from its abuse and illegal use.
