lol i think what you are saying is u got a 1.5 grams of shrooms and u want to take it after acid.... Well taking both at the same time would be ok but dont take them after eachother because you will quickly build a tolerance of the ACID and then the shrooms wont work. I suggest just eatin them at the same time so that you get the full effects. and Yes, eating 1.5 grams of shrooms and whatver amount of acid will fuck u up.
