for me, its full effects kick in between 15-30min and last around 4-6 hours depending on the dose it may last longer but if you don't have a tolerance 1mg will probably be noticable for a good 6 hours is my guess
Careful not to take too much as Clonaz is pretty potent and it will put u on ur ass no problem! I've ended up in hospital a few times due to blacking out on Clonaz...
