ScienceDaily, 2 August BMJ Specialty Journals. Retrieved November 9, from www. Neuroscientists have been researching the effects of cannabis on the adolescent brain.

Just a Game? It was about 50 milliliters, or the size of a kid's juice box. The researchers don't know why light-to-moderate pot use might subtly improve lung function. It could be that marijuana users inadvertently train themselves to be good at the inhalation and exhalation test because they "practice" deep breathing when they smoke pot, Kertesz told LiveScience. The airflow increase, then, is not necessarily an indicator of healthier lungs. At higher levels, this tiny increase seems to disappear and lung function may decrease, Kertesz said.
The study included few heavy users, which may be one key to why pot smoking isn't as harmful as tobacco smoking. But before you start lighting up, do remember you have other body parts. The main active chemical in marijuana is deltatetrahydrocannabinol, or THC.
If you have the slightest concern that you have developed a physical or mental dependence on marijuana, be proactive. Ween yourself off of daily use. Take a tolerance break and recalibrate your system. If this becomes too difficult, it is possible you are among the 9 percent. Research is mixed on this question. According to this study, earlier research did not control for alcohol use. Does this mean daily consumption of cannabis is OK?
The research does not say that. The data is not definitive on what longtime daily use does to cognitive development. Stuart Gitlow, a professor at the University of Florida, is an addiction specialist and an ardent opponent of the medical use of marijuana, saying it promotes a loss of attention, focus and concentration.
While the medical community continues to study the issue, one thing is clear: Young, developing minds should refrain from cannabis use. And daily consumption for an adolescent or teen is not advised. Similar to morning use of alcohol among alcohol-dependent individuals, morning use of marijuana may indicate dependence and increased cannabis-related impairment, according to a study in the journal Addiction and Research Theory.
So if this is one of your habits, now may be the time to wean yourself from it. There are potential negative outcomes, but not in everybody. While it is true that daily consumption will irritate your lungs and give some users a chronic hacking cough, research shows that smoking marijuana does not cause lung cancer.
