Does holding it in cause brain damage

[beachguy in thongs]

Just to add, THC is absorbed through your lungs into your bloodstream as soon as you breath it in. Keeping the smoke in any longer only allows the dangerous carcinogens to enter your bloodstream.

Does holding it in for long as possible and then blowin thru ur nose bad for ur brain, i dont think so but my friend says it does

your friend is VERY MISINFORMED
i would consider hanging out with more inteligent people
any one that dumb can deff. get you in trouble
there is no evidence that cannibis causes brain damage..
it does not cause lung cancer and IS THE MOST THERAPUTICLY SAFE SUBSTANCE KNOW TO MANKIND.
so keep on toking and tell your friend to stop listning to the gov't and DARE they are bold faced lying corupt lowlife's `

hotboxing i dont think it is its basicly replacing the airflow to you brain and body with THC so itturns making you higher and for holding it in no brain damage unless it was for like 10 mins. straight it would be like drowning
