Use these independent resources for reliable drug-testing guidance and support with substance use or mental health. Our legacy substance pages were primarily about detection timing and products marketed to affect test outcomes, so we are replacing them with neutral, trusted sources.
Drug-testing information
For information about home drug screens and their limits, read the FDA’s guide to home-use drug tests. For regulated workplace testing, see SAMHSA’s workplace drug-testing resources. You can also read our guides to testing methods and unexpected screening results.
Find treatment and support
SAMHSA’s FindTreatment.gov helps people locate substance-use and mental-health treatment services in the United States and its territories. SAMHSA’s National Helpline offers free, confidential treatment referral and information in English and Spanish at 1-800-662-4357. TTY: 1-800-487-4889.
If you or someone else is in immediate danger or experiencing a medical emergency, call 911 or go to the nearest emergency department. For mental-health crisis support in the United States, call or text 988.
