LSD is a psychedelic, unlike Oxycodone which is an Opiate. In my experience, LSD does not have a sense of euphoria like pills do. It's more neutral, but when you are having an amazing trip, well, you feel amazing and feel a natural high, a natural euphoria that comes with such positive thoughts and feelings.
Many people, including myself, find smoking Cannabis on LSD to be a little hectic. It can make you trip so much harder, and can sometimes cause you to become anxious, and uneasy due to Cannabis's infamous effect of causing paranoia. This, coupled with the mindfuck that is LSD, can cause you to have a bad time. Not that you can't smoke and have a good time, you certainly can, I just highly recommend smoking an hour after the peak, when you are coming down. Me and my buddies love to smoke a blunt after a trip. It brings us back up a little, but doesn't make us freak out like it would if we were peaking.
If you've never taken Psychedelics before, you are in for a ride. Start low. LSD is a drug that at low doses can make you forget you even took anything. The first time I tripped, was on one single blotter, probably around 75mcg, and at times it felt like I wasn't on anything, but then I realized "Oh wait, I am in fact tripping a little". It's best to start with an experience like this, just to get the lay of the land of what a psychedelic experience has to offer you. If you enjoyed it, and want more, then you can experiment with heavier doses. I strongly advise you never dose more than double what you are use to. For example, if you enjoy taking 3 doses at once and want to dose on a higher amount next time, I wouldn't recommend taking more than 5 or 6 doses. Also, keep in mind, doses vary in Mcg. So, if you like Blotter A because it only requires 2 tabs to reach that perfect feeling, you may not like Blotter B because it's weaker and requires up to 5 tabs to reach the same feeling.
Just be safe, and be comfortable. Do it in a small group, no more than 3 or 4 people who you trust and know will be able to help you if need be. Give yourself a window of 10 hours from the time you dose. Trips can last up to and over 14 hours at higher doses, but if you are dosing on a tab or two, even 3 or 4, it will most likely only last a few hours, more along the lines of 7 or 8 from start to finish, depending of course on the potency of the doses.
