I have a friend that smoked weed with us and the stuff we had was 25% THC and we are daily smokers but this friend isnt, he smoked with us every round which was around 5 times smoking from a bong. He started to get really pale and said he couldnt feel his body. I think that he was just really high but he is convinced it was an allergic reaction. He says that he still cant feel his legs even though the last time he smoked was two days ago. He has smoked other types of weed with us but this was different, is it only because its stronger?
