Crystal Meth Smell
Crystal Meth smell is caused by the many toxic chemicals used to create this drug. The production of Crystal Meth usually can result in strong odors. These odors can smell similar to cat urine, fingernail polish, a hospital (due to the common use of ethyl ether as an anesthetic), paint thinners, paint removers, adhesives, and cleaning fluids. When crystal meth is smoked, there is a slightly sweet smell emitted. However, only experienced users can detect the slight scent of Crystal Meth when it is smoked.
A Crystal Meth lab can have a strong uncommonly sweet smell too; not like a perfume, but something more like a lightly scented cleaning chemical. There is a point in the process where it may smell like a gas leak or rotten eggs. Some of the odors related to a Crystal Meth lab have been described as smelling like:
Auto parts cleaner
It is important to note, Crystal Meth lab homes that have been allowed to air out for some time may not have any detectable Crystal Meth smell or odors. The absence of odor in a home does not mean the home is not contaminated.
