Medic has like menthol and camphor in it, so does vicks, vicks used to have pseudoephedrine hydrochloride in it, (a stimulant), but they took it out cause it was being abused,
best i can understand the smell is just very pleasant when rolling, but you can get high off the "chroming" if you fully breath it in as it comes out of the can, but thats kind of junkie, similar to sniffing paint, bad for brain cells, where as just smelling it off a doll isnt so bad for your brain if at all, i mean vicks says you can use it as often as needed and its essentially the same shit, i always take a can with me, if you can buy it from FAL in a six pack its way cheaper,
but yeah, anyway, if you want something fucking intense, (and dont do this if you arent completely fucked on pills, it sucks) spray it under your underarms, feels pretty awesome, never tried the small of the back but i will next time
anywho, enjoy the medic,
