Yeah bro im 20 and I smoked for the past two years heavily no issue at all, everything was great and it did what it was supposed to. Recently the past 6 months I started to get super bad anxiety & paranoia from smoking even if it was just one tiny puff. Really fucking sucks because I love weed but its just not worth smoking because of how unejoyable it is. I hope it gets better for the both of us over time. Honestly my only advice is - if it happens everytime you smoke no matter what strain probably best to just take a full break for a while or if you haven't you should try mixing in ~ half CBD half THC. That worked for me for awhile but now I cant even smoke a few specs of normal weed w/ a full CBD bowl.
