Hi,
Thanks for posting in HCM.
I understand your concern.
Meth (methamphetamine) is a strong central nervous system (CNS) stimulant that is mainly used as a recreational drug. Smoking meth could get tested positive when done very next day, since intranasal and smoked methamphetamine are well absorbed.
Following its administration, peak methamphetamine concentrations are seen in 2 - 3 hours and the mean elimination half-life is 10 hours (range 6 - 15 hours).
Positive results generally indicate use within 1-4 days, and sometimes could be up to a week.
Hence, it would be better to get tested for after a week, in case you want the results to be negative.
Hope the information provided would be helpful.
All the best.
