Mixing Caffeine and Mephedrone (meow)
Caution
Two stimulants strain the heart and can make you anxious and uncomfortable. Skip the caffeine, or keep it light.
This combination of stimulants is not generally necessary and may increase strain on the heart, as well as potentially causing anxiety and great physical discomfort. However, individual responses to caffeine can vary significantly, often influenced by factors like habitual versus occasional usage.
The risk here is to the body — breathing, heart, temperature or organs. Set limits before you start, because this kind of harm does not announce itself in time to react.
