Cannabis stocks could see higher highs on new legalization efforts.

Just last week, according to Marijuana Moment, Rep. Dave Joyce (R-OH) and House Minority Leader Hakeem Jeffries (D-NY) introduced the Preparing Regulators Effectively for a Post-Prohibition Adult-Use Regulated Environment Act (PREPARE) Act.

“With nearly every state adopting its own set of cannabis reforms, an end to federal cannabis prohibition is inevitable,” Joyce, co-chair of the Congressional Cannabis Caucus, said in a press release. “Now is the time for the federal government to respect the will of our constituents and begin the conversation on fair and effective cannabis regulation. The PREPARE Act will give lawmakers a bipartisan platform to legislate not only a fair and responsible end to prohibition but also a safer future for our communities.”

While investors can always buy into pot stocks, like Canopy Growth (CGC), Tilray (TLRY), Flora Growth (FLGC), or even cannabis dividend stocks, like Innovative Industrial Properties (IIPR) and AFC Gamma (AFCG), ETFs offer greater diversification at less cost.

Some of the top ones include:

ETFMG Alternative Harvest ETF (MJ)

With an expense ratio of 0.75%, the MJ ETF tracks the Prime Alternative Harvest Index, designed to measure the performance of companies within the cannabis ecosystem benefitting from global medicinal and recreational cannabis legalization initiatives.
