CBD-infused shots, beers, and other alcoholic drinks have started to be produced and I have seen claims online that mixing CBD and alcohol can intensify each other’s effects, resulting in changes in mood and behaviour, yet it can help with alcohol addictions.
One study of 10 people found that when participants took 200mg of CBD with alcohol, they had significantly lower blood alcohol levels than when they consumed alcohol with a placebo (Consroe et al. 1979), however, combining alcohol with CBD caused significant impairments in motor performance and alterations in the perception of time.
Compared to placebo, alcohol and alcohol plus CBD, but not CBD alone, produced significant impairments of motor and psychomotor performances, overestimations of time production and subjective responses indicating an accurate self-perception of their intoxication and deficits. The combination of alcohol plus CBD resulted in significantly lower blood alcohol levels compared to alcohol given alone, however, there were few differences observed between the pharmacological effects of the two alcohol conditions.
The point I am making is that the study found that although CBD being added to alcohol lowers blood alcohol levels the pharmacological effects of the alcohol remain the same as without CBD. Although CBD does not have psychoactive effects on its own, it appears to me if I am interpreting the results correctly, that CBD speeds up the metabolization of alcohol, hense lower blood alcohol levels, yet the potency of lower blood alcohol levels is elevated too. Which if you think about it could affect driver blood alcohol testing limits?
The last point I made about driver testing is beside the point (in a way), but what I am wondering is What is the scientific stance on addiction therapy with CBD?
