Sant, eller rent jävla skitsnack!
Till GuA:
"Cannabisberoende är ur vissa aspekter svårare än andra drogberoendet. Peter van Dalen jämför med heroin. 60 procent av cannabispatienterna som söker på Jellinek har psykiatriska problem medan bara 20 procent av heroinpatienterna har det."
Detta säger inget om orsaksamband d.v.s att cannabis _orsakar_ psykiska problem. Som du säkert vet så har t.ex. utslagna och uteliggare psytiska problem från start och sedan fastnar dom i drogmissbruk.
Om cannabis som en beroendeframkallande drog:
"When human subjects were administered daily oral doses of 180-210 mg of THC - the equivalent of 15-20 joints per day - abrupt cessation produced adverse symptoms, including disturbed sleep, restlessness, nausea, decreased appetite, and sweating. The authors interpreted these symptoms as evidence of physical dependence. However, they noted the syndrome's relatively mild nature and remained skeptical of its occurrence when marijuana is consumed in usual doses and situations" (1)
"Indeed, when humans are allowed to control consumption, even high doses are not followed by adverse withdrawal symptoms" (2)
Om cannabis, minne och hjärnskador:
"While there is general agreement that, while under the influence of marijuana, learning is less efficient, (3) there is no evidence that marijuana users - even longterm users - suffer permanent impairment. Indeed, numerous studies comparing chronic marijuana users with non-user controls have found no significant differences in learning, memory recall or other cognitive functions. (4)"
