Anything is possible Ive actually experienced alot of what you're talking about . But I remember a few instances when i had to actually call people and ask when the last time we had smoked mary j (which had been years prior to incident ) because I really felt good and high for a minute or so. Never realized it was one major sign, but it happen many of years. Id ask myself dam when did I last smoke, and sometimes wish I had something to smoke. lol If you ever felt that right there described hey, even more reason to get checked
