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.

The half-life of an active substance is the time required by a healthy body, with no previous drug use, to eliminate 50% of the absorbed substance. In the case of cannabis, the half-life is 96 hours or 4 days. This means that within 4 days the body has eliminated 50% of the initial dose. 4 days later, there will be 25% of the product left… Within 28 days, cannabis will be totally eliminated from the body of a person who has not consumed it regularly. Traces of decayed THC may be found in a regular consumer’s body up to 40 days after the last take. According to Dr Chamayou’s thesis, 18 months are needed to be completely cleared of cannabis.
