Friend fred uses thru an iv .. So does a few friends who notices right after using they vomit.. I guess its not the first time , has happened last year where 2 others caught.on just as quick. & now the same stuff or w.e is going around again.. Fred doesnt use much at all when he does like close to none . Isnt like some who go hard.. He doesnt so its not that.. Its the methamphetamine.. Does any1 know what this could possibly be thst causes the vomiting ? Its looks more clear than an off white .. But looks legit. Just wandering what this could be and how harmful if at all if its actually meth or just bullshit.. Thanks in advance
