This high happens swiftly and all at once. It's like standing in front of a wall, pulling out one of the bricks, then having the whole thing fall over you... gently.
Pretty strong effect but manageable. A little bit of this goes a long way. The high was pretty pleasurable and I felt like I was in control of what I was saying and doing, which sometimes is missing with similar strains with like effects. Other strains I've had like this can make you feel somewhat out of control, and too much of them can make you freak out. However, Purple Sour Diesel provides a good balance between being
pretty tripped out (ie: sight change and VERY amplified tactile sensory) and also pretty centered at the same time.
