Yes, Alcohol is a sedative drug. In drinking regularly a large amount of alcohol, one becomes an alcoholic within a few years. Alcohol is characteristically able to potentialize the effect of all other drugs it is mixed with. If one mixes alcohol with another or others drugs, one can very rapidly become a drug-addict.

A drug-addict is someone who takes drugs in order to solve problems created by taking drugs. S/he thinks that s/he can stop taking them whenever s/he wants, however, in spite of the harmful consequences caused by consuming drugs, s/he cannot. If the drug-addict experiences withdrawal symptoms he will think only about providing himself with drugs even if it means acting against his morals. The demand is so strong that anything linked with will, effort, love or morals gradually disappears completely. Lies, violence, aggressiveness, moral or physical suffering, self-harm, being afraid to take part in everyday life become the norm. Because of these evil acts, the drug-addict looses his/her self-esteem and goes deeper into loneliness and suicidal urges.
