A YouTuber known as Dorian Develops became dependent on cannabis as a teenager, and after years of daily use, he recently opened up about the sweeping changes he experienced after going six months without it. His account, reported by LADbible, paints a picture of a brain slowly finding its footing again, with improvements touching nearly every corner of his daily life. For Dorian, quitting was not simply about breaking a habit but about reclaiming the mental clarity he had not realized he was missing. The transformation he described was gradual but, by the six-month mark, impossible to ignore.
One of the most immediate changes Dorian noticed was a dramatic lift in the mental fog that had settled over his thinking. “I often had to read the same thing multiple times because my brain simply could not process it,” he said, describing the cognitive toll his daily use had taken. Once he stopped, information started sticking again and basic tasks that had felt laborious became manageable. The shift was not overnight, but the trajectory was clear and consistent enough to keep him motivated.
The gains extended well beyond reading comprehension. “It’s much easier to motivate yourself to go to the gym when you don’t wake up and immediately light up. You have more energy, mental clarity, and focus,” Dorian explained. He went on to say that ambition itself felt more accessible without the constant haze of the drug. “It’s also easier to set goals, be ambitious, and do bigger things when you’re not permanently in a brain fog from weed. My organizational ability and productivity have improved dramatically over the last six months, especially in the last three,” he added. For someone who had been using cannabis since his teenage years, this level of daily functioning represented a significant recalibration.
Mental health was another area where Dorian reported meaningful progress. “I noticed that my anxiety and depression were definitely amplified by smoking weed every day,” he said. This runs counter to a common reason people cite for using cannabis in the first place, namely that it helps them unwind and manage stress. For Dorian, the opposite had been true, and stepping away from the substance revealed just how much it had been contributing to the emotional instability he had long attributed to other causes. He described feeling “much better” overall once he removed it from the equation.
The physical improvements were equally noticeable. Dorian’s respiratory system had taken a sustained hit from years of smoking, and within months of quitting he began to feel the difference in real time. “I no longer run out of breath, I feel like I have much more lung endurance, I breathe more easily, and I no longer cough,” he shared. Beyond the lungs, the simple act of showing up to the gym consistently, something that feels nearly impossible for many heavy cannabis users, became routine once the morning ritual of smoking was no longer anchoring his day.
Research supports much of what Dorian described. Studies have found that cannabis use beginning in adolescence can reduce IQ by an average of 1.3 points, while other research has linked regular use to brain fog, shortened attention spans, and reduced memory function. At the same time, cannabis-derived products are increasingly used for legitimate medical purposes, and many countries continue to explore legalization as a public policy option, reflecting the complex and often polarizing debate around the substance. Dorian’s story does not land on either extreme of that debate but instead offers a grounded, personal account of what daily use cost him and what stopping gave back.
Cannabis withdrawal actually has a recognized medical name, cannabis use disorder, and affects an estimated 9 percent of people who try the drug, a number that climbs to about 17 percent among those who start using in their teens. THC, the psychoactive compound in cannabis, is fat-soluble rather than water-soluble, which means it lingers in body fat and can be detectable in a person’s system for weeks after their last use, unlike most other substances that clear within days. The endocannabinoid system, which THC mimics and disrupts, plays a surprisingly central role in regulating mood, appetite, memory, and sleep, which helps explain why quitting can feel so destabilizing before it starts to feel liberating.
