Here are Maine’s marijuana producer tax rates, in addition to its 10 percent retail tax. The Legislature overrode the price-based producer taxes that the voter initiative contained:
- $335 per pound of marijuana flower or mature marijuana plants;
- $94 per pound of marijuana trim;
- $1.50 per immature marijuana plant or seedling; and
- $0.30 per marijuana seed.
