My colleagues and I at UC Hastings made a series of nonpartisan, informational videos on the California propositions on the November 2016 ballot. Here's a video made by my colleague Marsha Cohen, an expert on food and drug law, about Prop. 64, the legalization of marijuana:
On this blog I make endorsements as well, and my recommendation would be to vote Yes on 64.
In 2010, there was a legalization proposition on the ballot which I supported, Prop 19, and it failed by a fairly narrow margin. I supported that one even though I found it problematic and vague: Prop 19 legalized personal use and limited cultivation of marijuana, but left the business end unregulated and up to the counties. As a result, it was unclear how much we would gain in tax revenue.
Prop 64 offers a much clearer legalization regime. Flowing from the recommendations of the Blue Ribbon Commission and relying on the experience of Colorado, Washington, Oregon, Alaska, and DC, it has set realistic price points and tax rates on sales, thoroughly regulated cultivation, possession, and sales, and provided safeguards for sales to minors.
Let's talk about the money first. The Legislative Analyst's Office anticipates gains of many hundreds of millions of dollars, up to a billion, in tax revenue. These gains are based on assumptions about patterns of use and commerce that we see in other countries and states. For substances, there is typically a group of hard-core users (See Philip Cook's analysis of alcohol: 60% of American's either don't drink at all or drink very, very little, and only 10% of Americans constitute the vast majority of drinking in the market, with an average of ten drinks a day.) Those folks will use (and pay for it) no matter what, and making sure that they buy (and pay taxes) lawfully is pretty essential. Which is why setting the price point and the taxes properly is important. It seems that this is a key consideration in the states that already have recreational marijuana: you don't want to tax too much, because that'll keep the market alive. But even though those states are considering lowering the tax, they still got revenue that far exceeded expectations, and the hope is that the same will happen here. Prop 64 sets excise tax at 15% for retail and 2.75-9.25 percent for cultivation. Sales tax for nonmedical will hover around 8%.
The proposition sets up a licensing program. Selling without a license will be an offense. Selling to minors would be an offense. Setting up shop near a school will be an offense. And, driving under the influence would be an offense.
The most convincing argument against the measure is a recent Washington state study showing a rise in THC-positive drivers involved in accidents. Here's the full study. But that someone is THC-positive does not mean that marijuana was a factor in the accident. THC is detectable in the blood up to three weeks from the time of use, and a positive finding does not mean that the person was under the influence of marijuana when the accident happened. The study took into account differences in levels of THC, but those are imprecise. Also, keep in mind that drivers were not tested for THC presence before the legalization of marijuana in Washington, so we don't have great comparative data (who knows how many people were THC-positive before legalization?) Moreover, the findings on THC alone are dwarfed by the findings on alcohol, or on alcohol and THC combined (in which case the causality issue is murkier.) The National Institute on Drug Abuse website claims that marijuana impairs driving ability, but cites a National Highway Traffic Safety Administration study that found that carefully controlled studies relying on measurements find no appreciable difference in driving. NORML, who is far from an unbiased group but who does cite unbiased research, cites far less convincing evidence of impairment under marijuana than under alcohol.
As for arguments for legalization, the existing prohibition regime has been far from successful in curbing drug use and has led to huge monetary and personal costs for people charged, convicted and incarcerated for growing and selling. We wouldn't be the pioneers of a different path, but it's a thoughtful effort and definitely worth a try. I'm going with a Yes on 64.
