Weed is also terrible for a sleep aid since it suppresses REM.

Is that true? I use it most evenings and still have vivid dreams every night.

From a quick Google search it looks like it depends on the strain and dosage. Also doesn't look to be super well studied. On an anectodal level, I tend to have more vivid dreams on a higher THC strain and a deeper sleep on a higher CBD strain but here's part of an article on the subject:

Acute administration of THC has also been associated with decreased REM sleep and increased slow wave sleep (SWS), similar to some animal studies [30, 31]. However, the effects on slow wave sleep and total sleep time are not persistent

Data regarding effects of cannabidiol or CBD on sleep are limited. Studies in rats injected with increasing dosages of CBD showed an increase in total percentage of sleep, with a decrease in REM latency at lower doses and an increase in REM latency at higher doses
