What illegal drug , not weed, has a strange odor that lingers on a person?

My older daughter came to visit me. When I opened the door and she came inside I smelled this odor I had never smelled before. She has been doing various drugs since junior high. I asked what the smell was but she laughed it off. I had her leave the next morning (long story). It was absolutely not alcohol or weed so what was it? Does meth have a lingering odor? She has done meth for many years and I don’t think she slept that night. I want to add that my younger daughter is sober, always has been and wants nothing to do with her big sister. I still love both of them.
