What is addiction?
We considered several factors in an attempt to explain and understand the causes of toxicomanie.Une thing is certain: there is no single cause of drug addiction. A person develops an addiction due to a combination of factors.
Genetic factors
Perhaps some people are genetically more vulnerable to the addictive drug can generate. Studies have shown that the risk of having a disorder associated with alcohol and other drug use is higher among those with a close relative has such a disorder (Glantz and Pickens, 1992). However, many people who are genetically vulnerable to addiction does not develop an addiction to drugs while others, who have no family history of addiction, do.
