Anyone can have a bad trip on cannabis, no matter how used to THC they are. Ingesting cannabis instead of smoking it, using strains with very high THC levels and almost no CBD, consuming marijuana contaminated with traces of fertilisers or other substances, or simply being somewhere that makes us feel uncomfortable are some of the factors that could trigger a bad trip. If you happen to experience any of those, we recommend consuming pure CBD weed since this cannabinoid counteracts the negative effects of THC such as the tachycardia or dizziness. Should you not have any high-CBD strains near, try to calm down, breathe, walk a bit and eat something sugary to get the pressure up.
