The tax stamps will have to be placed on all cannabis products that are subject to the excise tax, whether those products are used for medical or non-medical purposes.
However, Budget 2018 does specify that products with a very low concentration of tetrahydrocannabinol, or THC, that is to say 0.3% at most, will not be subject to the excise tax. They will not be subject to the excise tax and will not be stamped. They are not covered by the regime.
However, cannabis that is smoked and used for medical purposes will be subject to the rules from the 2001 Excise Tax Act and will have to be packaged according to regulatory standards. They will also have to have a tax stamp.
