Does one get a harsher sentence for hashish, as opposed to marijuana?
LOL, no clue. There shouldn’t be. IMO, same should apply to morphine and heroin.
" (b) Except as authorized by law, every person who possesses not more than 28.5 grams of marijuana, other than concentrated cannabis, is guilty of a misdemeanor and shall be punished by a fine of not more than one hundred dollars ($100)."
H&S 11357c gets a little more severe:
"(c) Except as authorized by law, every person who possesses more than 28.5 grams of marijuana, other than concentrated cannabis, shall be punished by imprisonment in the county jail for a period of not more than six months or by a fine of not more than five hundred dollars ($500), or by both such fine and imprisonment."
In this section, possession of more than 28.5 grams of marijuana can lead to 6 months and a 500 dollar fine. Again, it does not include concentrated cannabis. At the link, you can see the progression of penalties.
I believe hashish would be covered under H&S 11034 under Tetrahydrocannabinols, and possession would be a felony.
(20) Tetrahydrocannabinols. Synthetic equivalents of the substances contained in the plant, or in the resinous extractives of Cannabis, sp. and/or synthetic substances, derivatives, and their isomers with similar chemical structure and pharmacological activity such as the following: delta 1 cis or trans tetrahydrocannabinol, and their optical isomers; delta 6 cis or trans tetrahydrocannabinol, and their optical isomers; delta 3,4 cis or trans tetrahydrocannabinol, and its optical isomers. (Since nomenclature of these substances is not internationally standardized, compounds of these structures, regardless of numerical designation of atomic positions covered).
