The Spanish Scientific Society for the Study of Alcohol, Alcoholism and other Drug Dependencies, Socidrogalcohol, warns on the banalization of cannabis consumption and about the scientific evidence proving that the before mentioned consumption is associated with both organic and mental health damage, including:

  • Risk for developing addictive disorders. Similar to what occurs with alcohol, only 10 per cent of consumers develop the addiction, although the higher and repeated consumption associated with it implies an increased toxicity and a greater risk of suffering other addictive disorders.
  • Decline in motor coordination and decision making after acute using, which is associated with a higher accident rate concerning motor vehicle driving. The before mentioned risk becomes visible and more likely to occur when cannabis consumption goes hand in hand with alcohol and central depressant drugs use (tranquilisers or sleeping pills, among many others).
  • Decreased attention span, memorization and learning, which may entail a decline in   academic, job and sport performance, above all among young people and teenagers.
  • Cannabis consumption is associated with the increase in the probability of the emergence of psychotic disorders, mainly for people predisposed to them, as well as other diseases like anxiety disorders. The consumption interferes with the recovery in patients under psychiatric disorders treatment.
  • Higher consumption of other addictive substances. “Joint” smokers are more likely to drink large amounts of alcohol, as well as to use other drugs as cocaine. Continued cannabis use also interferes with the recovery from other addictive disorders (alcohol or illegal substances).
