Enjoying THC and alcohol at the same time can heighten the effects of both substances, meaning you might feel higher with a lower dose than you would if you weren’t drinking alcohol.It’s worth noting that consuming too much THC after or while drinking alcohol can sometimes lead to feeling nauseous. If you’re combining, please be sure to start with a low dose of THC. And while you won’t get a hangover from the THC, it won’t save you from an alcohol-induced hangover.
