Just as a comparison I tried 30mg harmine sublingually and oddly despite the effects of the harmine being felt significantly more than 100-150mg orally the duration of the DMT effects was much shorter. Tracers went away at about 9-10 minutes unlike 25-35 min with the oral harmine. It seems that the duration varies greatly from person mind you, this is just my reaction.

There was also a difference in the quality of the experience, nothing I can really verbalize but there was something distinct from the 2 times with oral harmine (8x smoking total)

I mean it all comes down to what you want and it is so amazing that you can pick whether you want a 3-5 min, a 7-10 min, a 30-60 min or 3-6 hour experience by changing how you take it.

One thing that I'd be interested in is whether raising the initial dose would increase the duration of the peak and total, I think it makes sense that it should. I have been using 10mg for all the experiments so for just to keep dose out of the variables (plus it is majestically visual without being too intense)

I'm really surprised with a second account of the slow onset because I experience the exact opposite. Normally it take about 20-25 seconds to get to the peak with DMT alone but when on oral harmalas it takes 8-12 seconds and I scramble to put the pipe down!

As of the making a day of it, I plan to try that.

Yesterday I took 100mg of harmine at 12:40pm and smoked the same 10mg at 7:10pm and 10:55pm with the experience still being extended, though slightly shorter than earlier in the day. The 7:10pm being maybe 25min and the 10:55 being around 20min. I actually went to work to do some paperwork at 4pm not really feeling anything anymore but appearently the RIMA was still active to some degree when I got back.
