Quick answer
There’s almost no research on delta-8 withdrawal specifically. Delta-8 and THC vapes act on the same system as regular cannabis, so people who use them often may get cannabis withdrawal: irritability, anxiety, trouble sleeping and low appetite, usually starting in 1 to 3 days, peaking around days 2 to 6, and easing within about 2 weeks. The FDA says delta-8 products haven’t been evaluated or approved for safe use and has received adverse event reports.

Symptoms, phase by phase
Evidence note: The timeline above comes from cannabis withdrawal research, not delta-8 studies. A 2020 meta-analysis (Bahji and colleagues) found cannabis withdrawal in about half of regular or dependent users, and Budney’s 2003 study found onset within 1 to 3 days and a peak around days 2 to 6. A SAMHSA advisory notes a review in which sleep difficulties and strange dreams persisted at least 45 days into abstinence. The FDA says delta-8 THC has psychoactive and intoxicating effects, that products haven’t been evaluated or approved for safe use, and that it received 104 adverse event reports from December 2020 to February 2022. Some products are labeled simply as ‘hemp’, which may mislead people into thinking they aren’t psychoactive.
