would be much better overall. As long as its inserted far enough up (or even better dissolved and inserted with a pipette) the effects will be comparable to insufflation
, minus the pain and with a longer duration and less nausea. If the capsule/rizla is not put far enough up then you can feel like you 'need to go' for hours, which can be very uncomfortable. Lube/vaseline/saliva helps this.
If swiy were to try to snort 2c-e though I would say that you should be very careful with dosages (likewise with rectal administration) as the effects can hit quite fast and hard. 2c-e is not the worst 2c-x to snort, but is still not very nice at all. From swims experience you get an instant amazingly painful zap in your nose as soon as you snort it (can cause gagging, coughing) and this pain gradually subsides over about 1-5 minutes. Luckily since the dosage is so low for 2c-e, the drip should be negligable and should not cause a sore throat. Severe pain and sore throats seem only apparent with 2c-x's like 2c-d where you have to snort 30-60mg. My advice would be to snort it softly and slowly (and even wet your nose before hand by snorting
a [really] minute amount of water), to ensure that the powder stays in your nose and is absorbed fully by the musous membrane, rather than ending up burning the back of your throat.
Dosage wise, 10mg snorted can produce about the same level as a 20mg oral experience in swims experience, but with about half the duration.
