Marijuana has been a recurring trend for ballot measures since at least 2010, though there were a few before then. From 2010 to 2023, 24 ballot measures legalized the recreational or personal use of marijuana. More than $174.83 million was raised between supporters ($146.98 million) and opponents ($27.85 million) of these ballot measures.
Before 2024, the most expensive marijuana legalization ballot measure was California’s Proposition 64, which voters approved in 2010. Proposition 64 received $27.14 million in contributions, including $25.07 million from supporters and $2.08 million from opponents.
