Drug Checking & Safer-Use Resources
GUIDE-WIDE SAFETY NOTICE: This guide is for recognition, harm-reduction, and emergency-reference purposes. Appearance alone cannot reliably identify a substance. Counterfeit pills, powders, vapes, edibles, and street mixtures may contain unexpected drugs. Do not taste, smell closely, burn, or handle an unknown substance to identify it. If poisoning is possible, contact Poison Control (U.S. 1-800-222-1222) or 911 for severe symptoms.
