Quoting BgdSdbmommy:" okay i am sure i am about to get hell for asking this question but i wanna try smoking pot i have never ... [snip!] ... do it with him and i do but i am afraid to.. but my question is if i dont do it all the time is it going to harm me in anyway?"
You're going to get a bunch of differing opinions.
Mine is that in general pot is not harmful. If you are constantly smoking, then it can have some lung effects, but that is because you are inhaling burned plant matter, not to actual THC in the weed.
If you are worried about it, try smoking with a vaporizer. You get the effects without inhaling the stuff that is harsh on your lungs.
