ATLANTA, June 10, 2021 (GLOBE NEWSWIRE) — Cannabis stocks have staged a rousing return in recent weeks after a quiet first half of 2021. Sales are on the rise this year as revenue and profits for many cannabis companies have increased significantly. During the global COVID-19 pandemic medical marijuana was deemed “essential,” which definitely had an impact on increased sales. U.S. legal cannabis sales grew 46% year over year to $17 billion in 2020. The total U.S. economic impact from marijuana sales in 2021 is expected to reach $92 billion – up more than 30% from last year – and upwards of $160 billion in 2025, according to analysis from the newly published MJBizFactbook.
