Good to know.

Smoking/inhaling: Burning or vaporizing the cannabis and inhaling the smoke into the lungs is the fastest route to the blood stream. Conventional wisdom is that holding in the smoke increases the effects felt. Recent research shows the opposite; it causes more harm to the lungs without increasing the amount of THC absorbed. Studies done in Australia indicate that 95% of the THC in cannabis is absorbed in the first few seconds of inhaling. Holding in the smoke longer just allows more tar and other noxious chemicals to be absorbed. Take small, shallow puffs rather than deep inhalations.

You didn't know that?

Waves · 08-05-2011, 02:13 PM

Ive heard both ways, but never saw any solid science on it till today. The most recent one i heard was 7 seconds was ideal but even thats too long according to this article.

Also, regardless of whether i had known it or not, its good for EVERYONE to know in the name of harm reduction.

don't forget, the efficiency of the average lung.

looked for info, but found nothing.

**Mafoo** · 08-05-2011, 02:32 PM

they said several seconds. thats more than a shallow puff imo. i prefer to take a fat one hold it for like 5 seconds and exhale.

lung function is related to surface area and absorption is a passive process, meaning that the higher the concentration(partia l pressure) of chemicalx inside the lung, the more checmicalx will enter the bloodstream. the surface area of the lungs is pretty much fixed, so to get the best effect you should take a more concentrated hit to get more stoned.

Someone linked something on here years back that suggested around three seconds maximum, I've always abided by that.

This just in: Smoke is harmful.

**Mafoo** · 08-05-2011, 02:55 PM

i feel like the butane fumes from the bic or w/e lighter are more harmful than the smoke itself

my_scatterheart · 08-05-2011, 03:02 PM

I don't

**Mafoo** · 08-05-2011, 03:05 PM

meh i just looked up the equation, the products are water and CO2. nothing too harmful, CO2 isnt a good thing though

I feel you need moar chemistry lessons, the only "fumes" from burning butane are carbon dioxide and water. Protip: ignite the lighter before inhaling, if it's worrying you.

Edit: boo, slow response.

**Mafoo** · 08-05-2011, 03:15 PM

well now i can just worry about fertilizers and flint fumes lol

Blacks are responsible for 40.8% of all domestic violence cases despite being only 12% of the total population.

Sir-Ex · 08-05-2011, 03:32 PM

Niggers you faggot, use the correct terminology before I lay verily unto your cheek the broad side of a tuna.

The Rev · 08-05-2011, 06:13 PM

Are they responsible for 40.8% of all domestic violence, or just make up 40.8% of domestic violence arrests and/or convictions?

Wow, wtf is up with the grammar

High heat destroys some of the THC in smoked cannabis (estimates vary). Vaporizers heat it more gently; the THC molecules decarboxylate and evaporate in a whitish vapor. A problem with vaporizers is with correct use.
