Check out Part 2: Making Medicine From Marijuanaand Part 3: Before modern medical science, most medicines were raw herbs or herbal concoctions of one sort or another.
Jan 23, Sabrina Richards Flickr, PabloEvans Marijuana is a tricky drug, alternately demonized as a gateway drug and lionized for its medical promise. And while the juries remain out on both sides of the coin, one thing is clear: According to the US Department of Human Health and Services, the number of people in the United States who admit to smoking pot in the last month climbed from This increase may in part be due to the lack of strong evidence supporting the suspected risks of cannabis use.
Indeed, though marijuana smoke carries carcinogens and tar just as tobacco smoke does, definitive data linking marijuana to lung damage is lacking. And a recent long-term study that seemed to conclusively link chronic marijuana initiated in adolescence to a lowered IQ in New Zealanders was quickly challenged by a counter-analysis that pointed to socioeconomic status as a confounding factor.
Take a deep breath Ina study at the University of California, San Francisco UCSF calculated that even Is weed as bad as they a single joint every day for 20 years might be benign, though most participants only smoked two or three joints each month.
A studyfor example, suggested that smoking marijuana may reduce the risk of tobacco-associated lung cancer, calculating that people who smoke both marijuana and tobacco have a lower risk of cancer than those who smoke only tobacco though still a higher risk than non-smokers.
Your brain on drugs There is some evidence to suggest that stoned subjects exhibit increased risk-taking and impaired decision-making, and score worse on memory tasks—and residual impairments have been detected days or even weeks after use.
Some studies also link years of regular marijuana use to deficits in memory, learning, and concentration. But not 4 months later, a re-analysis and computer simulation at the Ragnar Frisch Center for Economic Research in Oslo countered the Duke findings.
Ole Rogeberg contended that socioeconomic factors, not marijuana use, contributed to the lower IQs seen in cannabis users. Studies in both humans and animals suggest that people who acquiring a marijuana habit in adolescence face long-term negative impacts on brain function, with some users finding it difficult to concentrate and learn new tasks.
Notably, most studies on the subject suggest that while there may be negative consequences of smoking as a teen, users who begin in adulthood are generally unaffected. This may be due to endocannabinoid-directed reorganization of the brain during puberty, Hermann explained.
In addition to the consequences for intelligence, many studies suggest that smoking marijuana raises the risk of schizophrenia, and may have similar effects on the brain.
Other studies further suggest that weed-smoking schizophrenics have greater disease-associated brain changes and perform worse on cognitive tests than their non-smoking counterparts. Such conflicting reports may be due to the varying concentrations—and varying effects—of cannabinoids in marijuana.
Hermann found that the volume of the hippocampus—a brain area important for memory processing—is slightly smaller in cannabis users than in non-users, but more CBD-rich marijuana countered this effect. While data supporting the harmful effects of marijuana on its own are weak, some researchers are more worried about the drug in conjunction with other substances, such as tobacco, alcohol, or cocaine.
Furthermore, marijuana may not mix well with prescription drugs, as cannabis causes the liver to metabolize drugs more slowlyraising the risk of drug toxicity.But smoking marijuana can have some bad effects on your health, including making breathing problems worse.
The federal ban on marijuana makes it hard to study its effects on humans. Yeah marijuana is not that bad for most people but for others it can cause anxiety attack, respiratory issues, memory issues, some love handles, loss of motivation, psychotic episode.
If any of these things happen to you its time to stop if you can once you get going. 8 Reasons Why Smoking Marijuana Is "Bad" For You 20 years of research sheds an unflattering light on weed.
Society's preconception that "weed is bad" has slowly been changing over the years. We've seen evidence of changing attitudes towards weed to the south, with US states legalizing marijuana, in the growing merit of marijuana as a treatment of diseases, and the relaxed attitude towards cannabis in our own community, though that isn't exactly new.
Reasons they gave included marijuana had fewer unwanted side effects, it managed their symptoms better, and it presented fewer problems with withdrawal. One marijuana user, Conrad, age 47, of San.
