yeah i was scared when i first tried it just hold it upright and dont do it alot or hold it in and you wont freeze your lungs i think but i just sprayed it in front of my lips and inhaled it and i talked really low and then thought it was cool and did it for like 10 min. so then i put it down and stood up and almost passed out you feel like drunk and EXTREMELY lightheaded. its a shitty feeluing but sorta cool if you like it i guess but i say dont do it or just try it once cause the high lasts like 20 sec. and its hardly a high
