How does SWIY experience TIME when using any substance

[AceOvArts]

I posted this thread in another part of the forum but it was suggested more people might get to see it here so here goes....

I have just been reading a book (Making Time by Steve Taylor, not a great book by any stretch) about how during our life time seems to get shorter as we grow older yet when we are young seems to last forever. How when we experience a lot of new things time seems to speed up yet when we are sitting doing nothing time feels like it almost stops.
There was a small (2 pages) part that spoke about how exposure to certain drugs allowed us to experience the slowing down or speeding up of time.
What was of particular interest to me was how depressents seem to make time speed up (because they slow us down and therefore we experience less) and slows down while on things like DMT(though psycadelics are in a world of thier own and can go either way) and amphetamines because one seems to experience a whole lot more while influenced.

What I would like any SWIMmers here to do is share this feeling if it has made a particular impression on SWIY.
I know that many reports on the forum include these such feelings but it would be interesting to see how SWIY felt on a particular substance. If some substances produce BOTH speedup and slowdown of time and how consistant these feelings are.

Time has always been a paticular interest of mine and I certainly have felt in recent years that time is speeding up for me.
Thanks

Swim thinks it would be easier just to ask the mods to move the original thread for this sub-forum, as the original thread already has some replies to it.

SWIBoB used to joke about setting up an operant unit of time distortion experienced under the influence of DXM by conducting experiments that involved making users watch certain videos or conduct structured phone conversations and ask how long the experience was and compare it to the actual time passed. Nothing serious. Just used to joke about some of the absurd distortion SWIBoB and his comrades have experienced whilst swimming in cough medicine.

With dextroamphetamine SWIBoB noticed that while the feel of time is not altered his ability to track it properly is way off. Time seems to fly off the clock in unbelievable ways even without feeling like there's a Lamborghini is his grey matter.

Above SMIBoB enjoys the experiences which seem to lose time all together. Nitrous oxide is particularly good for this.
