Dr. Grinspoon Cannabis Strain

THC 22%
CBD 0.4%

Dr. Grinspoon is a pure heirloom sativa named after the famous cannabis activist, Dr. Lester Grinspoon. It often features 20-25% THC and produces focused and cerebral effects.

This sativa is an homage to one of the most famous cannabis activists and doctors around, Dr. Lester Grinspoon. Dr. Grinspoon is an Associate Professor Emeritus of psychiatry at Harvard. Back in the late 1960s, Grinspoon set out to prove that cannabis was a harmful recreational drug. However, when he dove into the research on the subject, he changed his mind. There was not enough scientific evidence to support the idea that cannabis is harmful. So, Grinspoon became an activist. Since the 60s, Grinspoon has gone on to produce a wealth of research papers and has spoken out publicly in support of cannabis on countless occasions. The Dr. Grinspoon strain is just the plant to pay respects to this cannabis legend. Cerebral and clear-headed, this sativa is known to enhance focus and cultivate powerful uplifting sensations. Bred by Barney’s Seeds from a pure heirloom strain, Dr. Grinspoon gives users a taste of what an unadulterated sativa is like. This strain produces very little bodily effects and can be as energizing as a strong cup of coffee. Patients with ADD/ADHD, chronic stress, chronic fatigue syndrome, and depression will appreciate the cerebral qualities of this strain. This strain is great for daytime medication and is a happy, sociable addition to a night out with friends. Dr. Grinspoon is best left to experienced growers. This plant has a very late flowering time and can be quite tricky to grow in cooler climates. It features an earthy tropical aroma, with hints of citrus and spice.
