Influence of Tobacco on Tetrahydrocannabinol Levels

https://www.vapormed.com/pdf/Cannabis%20II%20IT.pdf

Medicinal cannabis has attracted a lot of attention in recent times. Various forms of administration
are used, of which smoking is very common but the least desirable. Smoking cannabis
generates a large amount of unwanted side products, of which carcinogenic compounds are
the most dangerous. A common practice among recreational drug users, and to a lesser degree
patients who uses cannabis as medicine, is to mix the cannabis material with commercially
available tobacco in order to increase the burning efficiency of the cigarette and to reduce
the overall costs of the cigarette. In this study cannabis material has been mixed with tobacco
in order to determine whether tobacco has an influence on the amount of and ratio between
tetrahydrocannabinol (THC), cannabigerol (CBG), and cannabinol (CBN) administered while
smoking. A small-scale smoking machine has been used and cannabis mixed with various ratios
of tobacco was smoked. The trapped smoke was quantitatively analyzed by high-performance
liquid chromatography (HPLC) and the amount of THC, CBG, and CBN was determined for
each cigarette. We have found that tobacco increases the amount of THC inhaled per gram of
cannabis from 32.70
・} 2.29 mg/g for a 100% cannabis cigarette to 58.90 ・} 2.30 mg/g for a 25%
cannabis cigarette. This indicates that tobacco increases the vaporization efficiency of THC by

as much as 45% under the conditions tested.

Ummm, commercial tobacco is chemically designed to burn hotter.

A vaporizer increases thc inhaled without the abuse and poison.

superb paper - very interesting. im always slightly ashamed that i prefer smoking weed with tobacco (old habits die hard) - but this gives the practice some credence.

added chemicals aside, i also doubt whether smoking tobacco is any more carcenogenic than weed anyway - after all its all organic matter at the end of the day...

thanks storm shadow for keep posting up these great papers that you have access to.

nicotine usually kills not cancer... 99 % of the people dying because of smoking tobacco die from heart attack or a stroke

yup, but its quite more than that.

1g of tobacco to a 1g of weed. you get about 4 times more stoned and it lasts about that longer.

1 hit of weed mixed with enough tobacco is 4 hits to me

but most users use 2g of tobacco (two normal cigs) to 1 g of weed.
if its really good weed, a "normal" user might go up to 6g of tabacco and still getting strong hits.

and, frankly i cough more from straight weed (usually) and often if the weed is harsh its far more palatable with tobacco. (though im both a tobacco smoker from way back (still smoke cigs if i dont have weed or need to be more clear)
and have smoked tobacco mixed weed from the very first hit i took.

i like to call it the peaceweed of the east meets the peaceherb from the west.

but still, id think just curing the weed properly would solve all need for tobacco in just making it burn better..

should smoke a lot smoother (commercial tobacco is often bit harsh)

funny, though, they come to the same conclusions as i with just testing on myself lol

as the fact that tobacco burns at a different temp than cannabis (therefore sorta vaporizes the thc)

but this can be seen by just carefully observing the burning mixture.

yeah right but mixing it with the tobacco the most dangerous compound will be: nicotine. so why should anybody mix it ? mixing medicine with like poison aint clever to me.

edit : dunno if you were talking to me at all...

Very interesting read. Back when I used to smoke cigarettes, I always enjoyed rolling spliffs mixed about 50/50.

Another interesting topic is on the effects of tobacco after a smoke. My roommates and I would go smoke a cigarette afterwards to "boost." My best assumption is that the added nicotine buzz helps to enhance the effects of the cannabis.

I've always enjoyed loading up a nice hookah mixed with some bud. This study proves that more cannabinoids are released when smoking dried tobacco, but I wonder how the effects are with a juicy tobacco like shisha. Anyway, nice read. Thanks for posting.
