For millennia, people have relied on depressant drugs like marijuana and LSD to lift their spirits. Alcohol, cannabis, and opiates have all been widely utilised in India for hundreds of years. Such psychotropic chemicals, however, have taken on pathological proportions in modern times. The 2004 survey, on the other hand, had some methodological flaws. Only males were interviewed, hence there are no statistics on the prevalence of substance abuse among women. Only findings at the national level were possible due to the sample frame. Because of this, the state-by-state differences in the amount of drug usage remained unidentified. To determine the prevalence of all drugs, researchers relied entirely on a household survey. Drugs that are socially accepted but not legal are called ‘‘illegal” substances. As a result, it's impossible to rule out the possibility of underreporting and, as a result, underestimating drug use.
