Note that marijuana has become legal in a LOT more jurisdictions during the timeframe of this chart: it was illegal in every state at the start of that graph, and is now legal for recreational use in 24 states, including many of the largest. So this is despite it becoming much more available and much less risky to use.

My country has a particularly high rate of sugar consumption. Are we a nation with a sweet tooth? Hardly, as it's inversely correlated with alcohol consumption as measured via sales figures and the process of moonshine production is greatly enhanced by the use of sugar as feedstock.
Meanwhile there's a whole movement that aims to limit alcohol availability in stores. A noble pursuit, but a misguided one, as the reported increases in alcohol sales over the past years are actually a sign of people preferring to buy instead of producing their liquor now that they can afford it.
Prices varied wildly by geography and how savvy you were, but years before legalization it wasn't uncommon to buy weed for $60/8th aka $17/gram for 3.54g. That was weed of far lower potency than what you buy today in the dispensary. Adjusted for inflation and potency, if you were to buy an eighth today for $60 you would be effectively paying a quarter of that price - but nobody's buying $60 eighths in 2024: you can now buy _legal_ $60 ounces in some places and $140 legal ounces in most states. Again, adjust for inflation and potency and we're comfortably under 1/10th the price of years ago - of what was already a cheap drug! There's just no motivation for illegal sales if you're an occasional user.
