I smoked a wax pen sunday now ive been feeling numb every since (5 days). how long will it take until the numbness go away?

Numbness: Hi, If you feel that this was directly caused by the wax pen, meaning you smoked it and the same numbness has lingered for 5 days without smoking it again, you should see a doctor as soon as possible. Regulation on manufacture of pens and vapes can be highly variable and the concern would be that you had a reaction to one of the ingredients. Hope this helps.
