Smacks is a hybrid strain.
Public lab results give a good picture of its strength: 25 flower samples tested between 2021 and 2022 came in at a median of 28.1% total THC (the middle half ranged from 24.7% to 29.2%). That puts it at the strong end of the market, so newer consumers should start low. Potency varies by grower and batch, so always check the label.
