Hey Sankhar and welcome
Im glad you have had wonderful experiences with dmt. The preferred method of taking spice is by vaporizer. You can look around here for a few suggestions on different smoking devices and such but you will find a lot of people like to us a device called the glass sherlock vapor genie. I can vouch for this device and say it is amazing, a bit pricey though worth it
Do you live in Western Australia? If so, G'day mate

and you would be best looking into acacias, I think Acuminata is available and is a fairly great source of dmt. Read around there's TONS of information to get you started and will have you reading for agggess
