I am a marijuana smoker. I inhale/smoke, primarily. I smoke small amounts around 4/5 days per week. For the past 6 weeks, or so, I have been experiencing uncomfortable reactions. My main symptom is pressure, tingling, and maybe numbness in the right side of my head, near my temple and moving back toward the middle of my head. I wouldn't describe it as a headache, per se, it is more of a dull pressure which is noticeable bur not painful. I feel this sensation for days after I smoke.
