I never used coated aspirin, but likely should be ok. Guess it depends on what the coating is...

Does the active ingredient mention salicylic acid?
Rusty Trichome Reviewed by Rusty Trichome on . Aspirin: How long for effects? Ok I want to make this RMT make me some pollen. I just harvested most of one, leaving enough to get me some response from the plant. How long after applying the aspirin does it take to show the nanners....on the average. There is no intention of smoking what is left, but I still prefer something I know my body accepts. So keep in the flower room for how long after the application....probably will only get one application as the plant will use little water now. Thanks. Rating: 5
