Problems after smoking weed?

Could be either or. It depends on you really. If this continues to happen after you smoke, then its from the smoking. If not then it could just be a one time or uncommon affect you feel from smoking. But yes smoking usually does cause some affect like that, but its usually not that intense and your lungs heal very quickly. In about one day. If it lasts longer, then its a sickness, maybe u got it from sharing your bowl or blunt lol. Either way you should be fine, see a doctor if it lasts more than 2 days or gets worse
