I think my girlfriend smokes?

Our results provide support that cannabis use plays an important role in the development of psychosis in vulnerable individuals. Cannabis use in early adolescence should be discouraged. - http://www.ncbi.nlm.nih.gov/pubmed/21883099
The risk to develop psychotic symptoms and also schizophrenic psychoses is thus explicitly elevated for young people who use cannabis. - http://www.ncbi.nlm.nih.gov/pubmed/19080993

“Cannabis use during adolescence and young adulthood increases the risk of psychotic symptoms, while continued cannabis use may increase the risk for psychotic disorder in later life, concludes a new study published online in the British Medical Journal.” - http://www.sciencedaily.com/releases/201...184056.htm

Heavy marijuana use causes brain damage. - http://www.sciencedirect.com/science/art...190800219X

After using marijuana "Teens showed abnormalities in brain response during a SWM task compared with controls, even after 1 month of abstinence." - http://www.psyn-journal.com/article/S092...1/abstract

Long-term heavy cannabis use in healthy individuals is associated with smaller cerebellar white-matter volume similar to that observed in schizophrenia. Reduced volumes were even more pronounced in patients with schizophrenia who use cannabis. Cannabis use may alter the course of brain maturational processes associated with schizophrenia. http://journals.cambridge.org/action/dis...id=8389504

Our findings indicate long-term cannabis use is hazardous to the white matter of the developing brain. Delaying the age at which regular use begins may minimize the severity of microstructural impairment. - http://brain.oxfordjournals.org/content/...2245.short

Teens who routinely smoke marijuana risk a long-term drop in their IQ - http://news.yahoo.com/teen-pot-linked-la...ontainer-b

Informants also reported noticing more cognitive problems for persistent cannabis users. Impairment was concentrated among adolescent-onset cannabis users, with more persistent use associated with greater decline. Further, cessation of cannabis use did not fully restore neuropsychological functioning among adolescent-onset cannabis users. - http://www.pnas.org/content/early/2012/0...62e23b6cea
These results provide new evidence of exposure-
related structural abnormalities in the hippocampus
and amygdala in long-term heavy cannabis users and
corroborate similar findings in the animal literature. These
findings indicate that heavy daily cannabis use across protracted
periods exerts harmful effects on brain tissue and
mental health. - http://www.truecompassion.org/PDFS/Healt...nPsych.pdf

Despite relatively brief exposure, adolescent
cannabis users relative to their age-matched counterparts
demonstrated similar memory deficits to those reported in
adult long-term heavy users. The results indicate that
cannabis adversely affects the developing brain and
reinforce concerns regarding the impact of early exposure. - http://www.acceptandchange.com/wp-conten...rmacol.pdf


Marijuana abuse during pregnancy and adolescence represents a major health problem owing to its potential consequences on neural development. Prenatally cannabis-exposed children display cognitive deficits, suggesting that maternal consumption has interfered with the proper maturation of the brain. - http://www.futuremedicine.com/doi/full/1.../fnl.11.27



“For example, chronic marijuana use is associated with reduced hypothalamic release of gonadotropin-releasing hormone, decreased plasma levels of gonadotropins (follicle-stimulating hormone, lutenizing hormone, and prolactin) and testosterone, reduced spermatogenesis, and impotency in men.” - //onlinelibrary.wiley.com/doi/10.1002/cncr.24159/full

Those who had ever used marijuana were 2.4 times more likely to be diagnosed with types of testicular cancer called non-seminoma and mixed germ cell tumors. These types of testicular cancer come with a somewhat worse prognosis than the so-called seminoma tumors. - http://news.yahoo.com/smoking-pot-linked...50779.html
