Guanfacine is not a stimulant. The Wikipedia page doesn't say it explicitly but hints at that a number of times. It's spelled out here though https://www.nps.org.au/radar/articles/guanfacine-intuniv-for... DEA also doesn't care and https://dailymed.nlm.nih.gov/dailymed/drugInfo.cfm?setid=1c4... shows no potential for abuse and lethargy as common side effect. Also from experience - it doesn't feel even close to stimulants.
