OP: If you've had these negative experiences, and the blotters are strong as you say, then why not just take one single blotter each to start with? Acid is one of the psychedelics where you can redose during the trip by taking more blotter without having to up the dose for tolerance, and it also sets in quickly so you should have a good idea of how strong it'll end up being around the hour and fifteen minutes to hour and a half point. So especially since you'll be in an unfamiliar setting, and tripping for the first time around other people, you've had bad trips and the blotter is strong, and it's at a pool party where there may be people that you haven't ever met before, start low with a single blotter and then take another half or 3/4 or even a full second blotter then at the hour and a half point if you think it will help bring the trip to the desired strength without necessarily being too intense for that setting.
After all, you can always take more right? But you can't take it back once you've dosed high, should it turn out to be too strong.[/QUOTE]
Before I give some advice to the OP, I wanted to make a comment about the statement quoted. From all the information that I've ever heard, researched personally, or saw in different documentaries over the years about LSD, as well as from personal experience with the substance, your statement about tolerance is pretty far off. While it is possible to some extent to be able to eat more LSD after your initial dose to get a greater effect, there is a reasonably short window of time to make this decision. The first 1-3 hours after ingestion, depending on your makeup and extent of usage, your tolerance to LSD raises CONSIDERABLY compared to other substances. You CAN eat more if you like, but it will usually just prolong the trip and make it that much longer until you can go to sleep instead of adding to the intensity and depth of the experience. If you are trying to take a booster dose after the initial 2-3 hour window with the intent of making the trip deeper and more psychedelic - I would honestly recommend taking about 1.5-2X what your original dose was. If you took 1 tab initially, take 1.5 or 2 to make up for the quick buildup in tolerance. If you're only looking to extend the trip and not go further out there - just stick with 1 extra. LSD also has a considerably long lasting tolerance, up to 1-2 weeks before it returns completely to baseline, which is also cross tolerant with Mushrooms, so if you eat a large dose of L and then try to take some Boomers the next day - you might not get to where you were trying to go with your usual dose. At the same time though, LSD doses aren't exactly always guaranteed to be EXACTLY 100mcg on every hit - sheets do get laid improperly from time to time which can make 1 random dose in the batch 2-3X stronger than the rest, so that is something to keep in mind when eating more after you're already tripping regardless of how fucked up you're trying to get. Always be careful and know your limits. LSD can make you it's bitch if you treat it like a game, and eventually IT WILL, so make sure you know the SOURCE, STRENGTH, and most of all these day LEGITIMACY of your "LSD". Eating 5 hits of Acid is WAY different than eating a 5 strip of NBOMes. If you think for ANY reason what you have may not be true LSD - be careful when taking more than 1 or 2.
Some great advice for anyone and everyone getting interested in psychedelic compounds - INVEST IN SOME BENZODIAZEPINES AND LEARN HOW AND WHEN TO USE THEM ALONG WITH YOUR ADVENTURES! They could save you or a friend from mental hell one day. All it takes to chill out that anxious/paranoid feeling you can get on Acid sometimes is a small piece of a benzo - I usually try to take .25-.5mg of Xanex at the MOST. Anymore than that and it almost kills the trip for me. If the visuals are getting to overpowering and intense, a little piece of a benny is all it takes, and with Etizolam, Pyrazolam, and 2-ChloroDiazepam out and about in the RC market......there is no excuse these days in my book to not have these tools handy when tripping. I honestly deem it almost irresponsible to an extent. I had .5mg of Etizolam turn 12hits from the depths of anxiety hell to one of the most beautiful experiences of my life. Even experienced trippers like myself get caught off guard from time to time by exceptionally strong blotters or a little too much liquid going drip drop on your tongue by accident. : )))))) Also, it should be known that 9/10 times someone calls 911 because they're having a "Bad Trip" or it's just too intense for them...........when they take get them to the ER, the 1st thing that they usually do if you inform them that you've ingested LSD is give you an IV shot of Lorazepam (Ativan) or another form of IV benzo depending on the hospital. Around where I live, it's almost always Ativan. I've unfortunately had friends in the past do that dumb shit while we were tripping and I went along to look after them and keep them calm. If you're REALLY buck wild you might get some IM Thorazine tho...............I don't recommend that one. OOOOOOOOOOOOWWWWWWWWWWWWEEEEEEEEEEEEEE!
The last thing I wanted to say about LSD tolerance is that, at least in my personal experience, LSD seems to have a somewhat permanent kind of tolerance to me. Like I don't think that I could ever eat just 100-200mcg and get what I would consider desirable effects - I honestly might even be a little bit grumpy that I didn't take enough to get to where I wanted to be, especially if I was taking it to go and see an event like a musical artist that I really enjoy. I've discussed this with a lot of friends who are experienced and we all seem to have the opinion that LSD does have a very slight permanent tolerance that builds up over repeated us, but it's hard to really tell how much of it is true tolerance increase and how much of it is getting adjusted to the mental and physical plateaus of Acid so that what once was intense is now just kind of Eh....I'd wager to say it's a bit of both. I've personally ingested around 4-500 doses in the past 8 years or so and I personally feel that I have a permanent tolerance to the head space of lower dose Acid. Eating less than 5, unless I'm in a social circumstance where I have to deal with people and be semi-behaved, is slightly boring........I mean, don't get me wrong, I'm still in a great mood, I feel super good, music sounds nice, stuff looks cool - but less than 4-5 doses and I just feel kinda stoned with a little trippiness, I don't feel like I'm on Acid very much. I still will always have love for this compound regardless. There is nothing on this planet like your first LSD experience - I would pay good money to be able to go back and have that first time all over again. Enjoy it OP - the first few times are like finding Jesus for a Christian. Life affirming and BEAUTIFUL.
