I guess it would depend on is there still weed in said container or it was just used for that previously and cleaned but smells? Because feeding mealworm edibles to a reptile seems risky so I'd toss if there were still drugs in there but not if it was simply the odor. Or like someone else said find out how long food is in their system and go from there but THC in human systems lasts a long time so that's another concern. For the price of some worms I'd probably look for a new supply.
