Vaping out of a lightbulb

The other day i was skimming some videos on youtube and i saw one called how to make a vaporizer out of a light bulb or something like that. So in my curiosity i did it. So just to see if it worked i packed in some old old old oooolllddd bud that was smoked before but wasnt cashed and i got really really high off of it. I recently used some fresh chronic my friend picked up and in about one and a half hits it felt like i was kissing god.

i also read this thing about how its safer and crap and u get like 95% thc every hit.
is all that true?
because if it is i will never roll another joint or pack another bowl again in my life :rastasmoke:

get a real vaporizer, lightbulb vapes work but they break very easily
