4. Living up to its Limitless reputation

Modafinil, a drug used to treat sleepiness caused by narcolepsy and sleep apnea, has a fan base among grinders who recreationally use smart drugs to “upgrade themselves.” Now, an official study confirms that modafinil reduces impulsive behavior stemming from a variety of conditions, from food addiction to schizophrenia, ADHD and alcohol dependence. Biohackers report a crisp, soft clarity and concentration beyond one’s imagination when taking the drug, but its impact on impulsivity means it could be a better treatment for obesity driven by food addiction, drug and alcohol dependence, attention deficit hyperactivity disorder and anxiety than the meds currently on the market. Turns out that 15x uptick in patients over the past decade for off-label use may have been more than just recreational.
