Weed is woo too

[Lancero]

16. Lets have a look at the first 5 shall we?

Pregnenolone can protect the brain from cannabis intoxication.
Parental THC Exposure Leads to Compulsive Heroin-Seeking and Altered Striatal Synaptic Plasticity in the Subsequent Generation.
Stress-Induced Dopamine Response in Subjects at Clinical High Risk for Schizophrenia with and Without Concurrent Cannabis Use.
Marijuana and lung diseases.
Comorbidity of Severe Psychotic Disorders With Measures of Substance Use.


The first one relates to protection fron cannabis intoxication - Poisoning if you will. Not a study proving weed to be healthy.
The second? Well... "Parental THC Exposure Leads to Compulsive Heroin-Seeking" says everything we need to know about that one.
The third I'm not so sure about. But since it's researching both use and non use, lets just put that one as neutral.
The fourth, well... From the summary - "There is unequivocal evidence that habitual or regular marijuana smoking is not harmless."
And number five. Last sentance? The use of tobacco, alochol, and other controlled sustances, is higher in those with mild mental illnesses then shown by recent estimations.

These are only the first five studies, but it doesn't paint that good of a picture.
