Sweet Tooth was definitely a good strain for me to check out. Does have that slight hint of sweetness. For some reason I don't get that knocked out feeling, but more so just a mellow, chilled out high.
Everytime I vape with Agent Orange, I'm definitely feeling great up in spirits for the first hour. However, I tend to knock out after that, which I'm sure is when the Indica kicks in. Lasts about a good 2-3 hours
