Summary
Propylhexedrine is legally available as an over-the-counter nasal decongestant in the United States under the brand name Benzedrex. Recreational use typically involves extracting the drug-soaked cotton from inhalers, a practice that carries significant health risks that have not been extensively studied. Propylhexedrine produces more pronounced peripheral effects (vasoconstriction, cardiovascular strain) compared to amphetamines due to reduced blood-brain barrier permeability. Use extreme caution with dosing and avoid use if you have cardiovascular conditions or personal/family history of psychotic disorders. Always use harm reduction practices including accurate weighing, avoiding combinations with other stimulants, staying hydrated, and monitoring vital signs.
