| In addition, scientific analysis of cannabis suggests a continued increase in the level of tetrahydrocannabinol. |
| In America average concentrations of tetrahydrocannabinol, the psychoactive ingredient, doubled in the 1990s, as growers focused on stronger, more expensive cannabis. |
| Molecular studies have shown that tetrahydrocannabinol, the active component of cannabis, increases release of dopamine in the mesolimbic pathway. |
| Does this mean that hops also contain tetrahydrocannabinol, the active constituent of cannabis? |
| Mr. Speaker, as the member is aware with regard to cannabis, for instance, the active ingredient is THC or tetrahydrocannabinol. |
| But unlike pot, industrial hemp contains very little THC, or tetrahydrocannabinol, the chemical that gives marijuana its narcotic effect. |
