To me, the only true trip I think of when I use that term is either shrooms or acid. Years ago, I would trip on average about 3 times a month, nearly all LSD, the odd shroom trip. Fast forward till the internet made buying wet shrooms very easy and it was all legal and I was tripping more than once a week for a year. Then that source vanished but luckily I was able to obtain dry shrooms more or less straight away, but fewer opportunities meant it was averaging one trip a month. The expense was also a factor. LSD was unobtainable (ok someone will say they always got it but overall that was the picture).
Then suddenly just recently it was everywhere and it was back to a mixture of both that and shrooms, possibly on average twice a week. One week I had lsd for two days solid, topping up as it began to wear off, then 3 more trips during the week and another the following weekend. These were all pushing the barriers further and further - the most being the equivalent of 8 decent trips taken at one go (accidentally).
This led to me becoming very unstable and locked in a nightmare world of HPPD. Eventually I was taken into hospital for a detox when my opiate meds (prescribed for RA) went out of control. Now everything is back to normal and I'm not sure how frequently I'll trip. I haven't at all since going into hospital. My priority is really getting back to work and staying steady and getting something more useful out of life.
