Vicks

Only historically. No Vick's brand product has contained it since 2016. The only "brand" name I'm aware of currently is Benzedrex.

Benzedrex is not l-Methamphetamine, it is Propylhexedrine

Ah indeed, I misremembered. That is also a very similar compound, identical structure but more saturated carbon bonds (non-aromatic ring). It's always delightfully silly to get your own correction corrected!
