With THC levels that can skyrocket to over 20%, this strain is not for users who are unprepared or have no experience with marijuana. Like a nuclear reactor about to blow, Critical Mass will wreck users who are not careful. That said, this combination of Skunk #1 and the Afghani landrace strain provides users with such effects as full body relaxation, a sense of transcendence, and eventually heavy sedation. Those eyelids will droop, unwary users. Expect a sweet taste on the tongue coupled with dirtier, woodier aromas. Growers will appreciate this one’s short grow times and abundant harvests.
