† The Substance Abuse and Mental Health Services Agency (SAMHSA), has set "cut-off" levels when testing for marijuana, cocaine, methamphetamine, amphetamines, ecstasy, opiates, and PCP. First Check is manufactured to conform to those standards. Screening tests may not detect amounts of drugs in a urine sample that are below the cut-off level. Even though some level of drug may be present in a urine sample, the sample would still be considered Negative Result if the drug level is below the cut-off level.

Recent Developments:

Marijuana is being used in combination with other drugs of abuse and is a delivery medium for other drugs. Crack, psilocybin mushrooms, ketamine, and PCP are sometimes added to marijuana joints. Slang names for the combinations vary according to geographic locations around the country. Joints or blunts containing PCP are known as love boats, honey-dipped joints, happy sticks, sherms, or dust blunts. Dipping marijuana joints into other chemicals such as formaldehyde, embalming fluid, or formaldehyde mixed with PCP enhances the effects of marijuana and makes the joints and blunts burn longer. The PCP combination produces aggressive behavior in the users. Variations make marijuana smoking more unpredictable, particularly for novice users.
