Can smoking Marijuana once give u lung cancer?

I tried it, i never should have. A week and a half to three weeks alfer, i started having chest pain, not bad or anything. i decided to go to the doctor, not telling him that i did it, jsut to see if he thought it was anything major. He listened to my heart, and lungs and everything sounded normal. Its been almost a month and a half, ive been to the doctor another 2 times, them saying it is prob just a pulled muscle, and that my lungs and heart sound find. I still have a cough, pains in middle of my back, and chest. I had x rays done, it wasnt the bones or anything like that. I'm freeking out here, till today, i know it was a big mistake, i dont even know why i tried it. Im worried it's something serious. Do u think its related to smoking, or anything serious, plesae respond, im in need of releaving the stress.

Also, the pain isnt all the time, it;s on and off during the day, and never when i first get up. O and im 17, if that helps.

do you think lung pain is an indication of cancer? if you do think that please go to the nearest school or library and spend 4-10 years there reading books.

Did you cough a lot? maybe you did pull something sometimes muscles tend to take a while to heal. I find very unliklely that anyone could get cancer from just one hit and if you were allergic to it it would have happened when you smoked or shortly after not a week. My guess you gave your long a litttle burn its not used to and now its mad at you. If you went to the doctor like you said you should fine in time. You sond like you worry to much like me, just try to relax.

this guy has to be full of it.

Ok dude, one thing you should remember is paranoia can happen when your high, chill the hell out, your only perpetuating the problem by worrying about it....your fine, believe that and it youll see that it will come true, this is comming from someone whos had the same thing only worse,from coke, adderal and opium...so chill out man, its just bud....

man.... this guys full of shit.

you cant get cancer from one toke of pot.
grow some balls already.

and if it hurts, smoke more.

medical marijuana my friend

WAIT A MINUTE, DID THIS GUY JUST SAY.......HAHAHA.....

DOG, YOU THOUGHT YOU GOT CANCER FROM 1 HIT OF THE BLUNT?
HILARIOUS....

BUT ANYWAY, THE 1ST TIME, YOUR CHEST JUST MIGHT HURT A LITTLE. THAT JUST MEANS YOU ACTUALLY INHALED....EXCEPT, IT'S SUPPOSED TO HAPPEN AS SOON AS YOU HIT THE BLUNT, NOT A MONTH AFTER...I THINK THAT'S A CASE OF PUSSYITIS...

SOME PEOPLE CRAZY....

Well there buddy it seems as if you came across a potent strand of Marijuana.. Quit Bitchin and get some MORE!!!!! Sounds like some good shit!!!!

SOunds more like anxiety induced by feeling of gulit for this one time event. Many ppl experiment with drugs and while it may not excuse the behavior surely you must let the one time go and chaulk it up to experience. If it makes you feel better tell your doctor, family memeber or trusted friend. Stop worrying that it might be lung cancer which im sure it is not, and the symptoms will probably go away. Hey your human, we all make mistakes, now its time to move on with your life:)

no bro u cant get cancer from 1 joint gettin cancers takes time if u take it over and over again thats how u get cancer like for example if u eat chips and mcdonalds almost every day u need to eat it for like 1-2 years than it will develop not right away. u probally have pain from being in the cold or if u play alot of sports u might have pulled something but if the doctors asked u for a blood check and said ur fine than ur fine. because u can see if people have cancer through the blood because the cells are crazy and they l know something is wrong than they l ask u for a cancer test to see where the cancer is. i never had cancer i m just very scared from it so i do alot of research. by the way eat alot of fruit and take asparin every once in a while they reduce chances of getting cancer.
