2C-B: Severe burning of the nasal mucous membrane when sniffing. Slightly accelerated pulse, increase in blood pressure, increase in body temperature and decreased feeling of hunger; Nausea, sweating, dizziness, inner restlessness and cardiac arrhythmias are possible. Users report stomach and intestinal problems, slight allergic reactions, coughs due to increased mucus production and unwanted erections. Dilation of the pupils, reduced visual acuity, impaired ability to concentrate and react as well as sleep disorders can occur. Bad trips are more likely with high doses than with low doses, as the loss of control and "reality" can be perceived as threatening (disorientation, confusion and feelings of fear). Even after the effects have subsided, slight side effects can still be felt.
