Just listened to Seth Rogen's audible book (hilarious, and decent anecdata on shrooms particularly) and he would say shrooms are a lot more intense than LSD. Shrooms take control while on LSD you're "the pilot."
He has good genes, or a high tolerance.
I tried smoking around December, and realized I hated it. I liked it in high school. I couldn't wait until the effect went away. It's weird I kept trying it, and finally gave up. Was about to toss it, but hide it instead--too cheap to toss?
Then again real life has been scaring me for years. I wish there was a calming drug that was easy on the body.
Especially with the extremely high THC content of modern strains people often fail to recognize that weed is still a psychedelic in its own right.
Alcohol, for most people, will simply make you feel good (up to a point), but strong weed can often magnify strong emotions you have. During a particularly challenging time in my life I completely gave up weed because smoking only served to make me feel worse.
Like all psychedelics the negative experience can be useful, for example if you get very anxious when you smoke it's likely you have some other unaddressed problems, but for those that are just looking for an escape (and most people, myself included, are looking for this from weed) it can certainly make smoking during stressful times a bad idea.
A counterargument that a friend told me once: a psilocybin trip is like a wagon ride that takes you to what you need to see. LSD is like a jet plane that takes you instantly to where your brain wants to go.
I think it probably depends on the person. My first psilocybin trip was the most intense experience I've had, but then I had a lot that I needed to confront at the time.
In all there were three trips I would call "bad", I went to what I perceived as hell. The mushroom bad trip was nearly indistinguishable from the acid bad trips.
In all three cases I felt immense gratitude for the trips being over yet thankful for the experiences.
There is no reason to take more than this as introductory doses, and then you can make up your own mind.
