I developed acid reflux from swallowing weed smoke and then i took a break from smoking weed.then i started smoking again for 3 months and stopped.please am i going to be ok??im scared?

Maybe question to be asked: why do you return to smoking weed if you have had prior problem and now are "scared". Let your doctor know what has occurred, and I doubt severe issues have arisen but get reassured.

First thing to do is quit smoking weed. Marijuana is a psychoactive drug and will mess with your brain. MJ users are called stoners for good reason.
