There are several possibilities. They are not likely to be permanent. First, marijuana s active ingredients are oils and they stick to fat and come out irregularly this causes waves of altered feeling after smoking. There is panic, upset, even a PTSD like effect that can come from marijuana. Often there is rapid breathing along with that and the breathing causes people to feel slightly woozy, faint, tingly--we get about a question a day on this. The psychological effects can last indefinitely but that is not common. Much more likely people get over it in a week or up to a month. First, realizing what is going on sort of fixes it. Second, counseling or any treatment for anxiety can also fix it.
