Of course it's going to do some harm to your body.. your breathing in smoke but mostly anything harms you body. If you wanna get technically walking kills brain cells so how about that.This article is so misleading.
All the idiots that read this were prolly like; "duuuuuuuuuuuudes.. DUUUUUUDESSSS! MARY JANE DOESNT HURT YOUR LUNGS. MJ ALL THE WAYYYYYYYY"
Look closely at the title: No long-term lung damage from occasional marijuana use.
How much you wanna bet its the same story with cigarettes? (depending on what you consider 'occasional smoking')
In my country you can't go to jail for possesion or trafiking of marijuana unless you have more than 28 grams (1 ounce). I have been pulled over with weed on my and all the cops did was throw it away, no fine, no warning, no jail time.
Last summer I was in a car with 3 other people they had 150 extacy tabs, 14 grams of weed and 3500$ in cash. I've been going to court for over a year now and every time I go they remand me. I had a call from my lawyer the other day telling me that my chargers are going to be dropped on my next court date so you can shove that 1-7 years up your ass. I was charged with trafficking and possession of an illegal substance. Not because of the weed, because of the tabs.
