From championship belts to cannabis advocacy, these fighters are changing the conversation around plant-based recovery in combat sports
Mike Tyson is not only a legendary heavyweight champion—he is also breaking new ground in the cannabis industry. His career is a vivid illustration of how attitudes and opportunities around cannabis in boxing have changed.
Anthony Joshua’s story demonstrates how a champion boxer’s relationship with cannabis can evolve from youthful experimentation to sophisticated advocacy. His experiences reflect a nuanced, modern approach to responsible cannabis use for athletes.
Shannon Briggs, former heavyweight champion, experienced a dramatic personal health turnaround thanks to cannabis. His advocacy and business ventures make him a prominent figure in the conversation about cannabis and recovery in combat sports.
Evander Holyfield’s cannabis journey offers one of the most powerful reconciliation stories in boxing. His partnership with Mike Tyson and advocacy for recovery-focused products illustrate broader opportunities for retired athletes.
As an active professional boxer, Arnold Barboza Jr. represents a new generation openly advocating CBD for athletic recovery. His stance signals changing regulations and growing acceptance of cannabis within professional sports.
The Association of Boxing Commissions’ Medical Advisory Committee stated cannabis is not performance-enhancing and recommended reduced penalties, referring to it as performance-suppressing. This scientific acknowledgment has led to concrete policy changes, most notably Nevada’s State Athletic Commission voted in 2021 to stop disciplining fighters for cannabis.
These regulatory shifts explain the dramatic difference in how Mike Tyson’s cannabis use was treated in 2000 versus 2020. The evolution from career-threatening suspensions to corporate-sponsored events reflects broader societal acceptance—70% of Americans supported legalization in 2023, up from 16% in 1990. This policy transformation is creating space for athletes to be more open about their cannabis use and business interests.
Current cannabis testing in boxing relies primarily on three methods: oral fluid tests that detect recent use, urine tests that can detect use for varying periods depending on frequency, and the World Anti-Doping Agency’s threshold of 150 ng/mL for THC metabolites. However, research confirms that extreme environmental exposure to secondhand smoke can produce positive THC tests in oral fluid up to 3 hours post-exposure in unventilated conditions.
Detection windows vary widely by frequency and dose; heavy daily users can test positive for 30+ days, whereas occasional users may clear much faster. The inconsistency between state regulations—as of 2024, 24 states and DC have legalized adult-use cannabis; 38 states and DC have legalized medical cannabis—creates a complex patchwork that fighters must navigate when competing across jurisdictions.
The transition from boxer to cannabis entrepreneur has brought remarkable financial success for legends like Tyson, Holyfield, Briggs, and Joshua. Their ventures have proven that athlete-endorsed products resonate in a crowded marketplace.
Boxers seeking cannabis for post-fight recovery must carefully choose cannabinoid ratios and terpene profiles. Understanding the difference between THC and CBD is essential for balancing anti-inflammatory benefits with performance safety.
The normalization of cannabis in boxing extends beyond individual athletes to cultural acceptance. Former opponents becoming business partners, active fighters openly discussing CBD use, and regulatory bodies acknowledging cannabis as non-performance-enhancing all signal a fundamental shift in the sport’s relationship with plant medicine.
This cultural transformation is documented regularly in cannabis news coverage, which tracks policy changes, athlete advocacy, and industry developments. For fans wanting to stay updated on these evolving dynamics, subscribing to Herb Hype provides bi-weekly insights into athlete ventures and regulatory shifts.
Research confirms cannabis decreases reaction time and disrupts hand-eye coordination, making it performance-suppressing rather than enhancing. This scientific reality contradicts the historical rationale for cannabis prohibition in sports and supports the Association of Boxing Commissions’ position that cannabis should be treated differently than traditional performance-enhancing drugs.
The focus is shifting from prohibition to education—helping athletes understand proper timing, dosing, and product selection for their specific needs. Whether using CBD for recovery or THC for post-competition relaxation, informed choices based on scientific understanding are replacing blanket prohibition.
At least five championship-level boxers have documented cannabis connections: Mike Tyson, Anthony Joshua, Shannon Briggs, Evander Holyfield, and Arnold Barboza Jr. Tyson admitted smoking before his 2020 fight and co-runs cannabis brands that have generated about $50 million in first-year revenue. Joshua discussed teenage cannabis use and now invests in CBD companies. Briggs and Holyfield advocate for CBD recovery benefits. Barboza Jr. publicly promotes CBD for active athletes.
Regulations vary significantly by jurisdiction, with major policy shifts occurring recently. Nevada’s State Athletic Commission voted in 2021 to stop disciplining fighters for cannabis. The Association of Boxing Commissions’ Medical Advisory Committee officially recommends cannabis is not performance-enhancing and positive tests should not result in the same penalties as PED violations. Other states maintain varying thresholds and policies. The WADA threshold is 150 ng/mL for THC metabolites.
Active fighters primarily use CBD for its anti-inflammatory properties and recovery benefits without psychoactive effects. Retired fighters often use THC for pain management and sleep improvement. The key distinction is timing—many athletes avoid THC during active training periods but may use it for post-competition recovery. Athletes focus on specific cannabinoid ratios and terpene profiles to match their recovery goals. CBD-dominant products are preferred during training cycles to avoid performance impairment.
Mike Tyson’s Tyson 2.0 and Ric Flair Drip together generated about $50 million in their first year and have projected around $160 million in combined revenue. Shannon Briggs operates Champ RX CBD following his health transformation. Evander Holyfield partners on “Holy Ears” products with Tyson. Anthony Joshua is a shareholder in Love Hemp as of 2021. These ventures span flower, edibles, CBD oils, and topical applications, leveraging athletes’ credibility.
Yes, research confirms that extreme environmental exposure to secondhand smoke can produce positive THC tests in oral fluid up to 3 hours post-exposure. This occurs primarily in unventilated spaces with high-THC cannabis and prolonged exposure. Detection windows vary widely—heavy daily users can test positive for 30+ days, whereas occasional users clear much faster. The WADA threshold of 150 ng/mL for carboxy-THC helps reduce false positives. Testing vulnerabilities highlight the need for refined protocols distinguishing actual use from environmental contamination.
