Maui Waui, sometimes called Maui Wowie, is a mostly Sativa hybrid that was considered a top of the line strain when it first appeared in the 1960s. The argument, ‘pot wasn’t as potent back then’ generally refers to a time before Maui Waui was developed.
Maui Waui was one of the first strains with greatly increased THC content. In the 60s, when Maui Waui was bred, the THC content of an average marijuana strain was quite low (almost always under 8%). Maui Waui featured THC content well into the teens and quickly became one of the most desired strains available.
These days, it is considered to be a middle to high grade medication that provides a typical Sativa high with a few Indica perks. Other strains (along with new hybrids) have caught up and even surpassed this legendary strain in THC content
