I have Passionflower, Damiana, Mugwort, Calendula, Lemon balm, Spearmint and peppermint.
What do you think I should use and in what proportions should I mix to make a decent smoke?

Experiment with lots of different blends. Enjoy.

2 parts Damiana, 1 part Spearmint, 1 part Peppermint. That's what I would go with.

I usually just smoke Damiana with a little Blue Lotus mixed in as a herbal cigarette.

Thanks Dioxippus ill try that mix tomorrow
Just done a mix of 600mg Passionflower, 60mg Damiana, 20mg Calendula, 20mg Mugwort and 300mg spice. Drying as we speak so will try later tonight

lets hear about it!
Im about to make bufo-dmt changas tommorow, but unfortunately I only have salvia leaf
Ill have to pick up some more flavourful herbs... im still trying locate a nutarlist store where these can be purchased.
I think it would be a waste to buy something like 'spearmint' leaf online, and you'd almost certainly not want to buy sprayed/pesticide herbs from a grocery mart.
So it seems like a natural/organic store is the way to go

Well the changa tasted really nice and smooth, didn't have too much as my mouth is still healing from an abscess and i'm on a load of tablets to heal it. If it's sorted by next week i'll see if i'm brave enough to try a breeakthrough dose on this mix..

I'm lucky to have my fiance work in a herb/spice distributor, spoiled for choice really And the peppermint is 100% organic tea with no additives. Spearmint is picked fresh from the garden and slow dried for smoothness

lucky you
