The mysterious, smelly hybrid Chemdawg packs a punch both physically and mentally. Not for first-timers—this cannabis strain produces an energetic cerebral high coupled with a full body buzz. Those with PTSD, anxiety, insomnia and chronic pain can benefit from this strain’s effects.

Although popular, Chemdawg is tough to get a good handle on. Nobody knows for sure where this cannabis strain came from and while thoroughly enjoyed by consumers, they seem to have differing opinions on when to best use it.

Chemdawg’s origins are muddled, but most stories involve a Grateful Dead concert and the exchange of seeds among a group of tight-knit hippies. While we aren’t certain of Chemdawg’s lineage, it has produced some of the most well-known marijuana strains in circulation today, including OG Kush and Sour Diesel.

Chemdawg is a marijuana hybrid, but there doesn’t seem to be solid consensus on whether it’s even-keeled, indica-leaning or sativa-dominant. Despite this, two things are certain: This is one stinky strain with a strong, diesel aroma and even stronger mind and body effects. With a THC content that clocks in around 20%, this isn’t a strain for beginners and even the most THC-tolerant users should practice caution.

This marijuana strain is said to magnify sensory experiences and produce a significant body melt. Some consumers find these effects overpowering and reserve Chemdawg for nighttime use. Others claim that the uplifting cerebral high makes it a great daytime companion. Based on these reports, if you’re trying this strain for the first time, it’s probably best to start at home.

Chemdawg’s heavy physical effects make it a good match for medical marijuana patients looking to relieve chronic pain or insomnia. This is also a great strain for stimulating appetite, and its euphoric effects can help with depression and anxiety.
