Effects can include euphoria, drowsiness, reduced heart rate, reduced respiration, increased sexual arousal and some numbness. Taking, or smoking a larger doses can bring about respiratory depression, slurred speech, headache, and light sensitivity.
An overdose can cause delirium, convulsions, hypertonia, hyperreflexia, vomiting, renal insufficiency, coma, and death through cardiac or respiratory arrest. It's not cool.
