Teetering dangerously close to being a "What drug should I take?" thread... but will see how it goes for now.
I actually enjoy all three products you mentioned. Amanitas are a bit odd but are not much like other psyches at all really - they make you feel kinda drunk and dissociated with a touch of psychedelia alongside. I've never dosed too high on them though so may get more interesting at those levels but for "average" doses (ie the amount they sell in a pack) it feels mostly a bit like a low-moderate dose of LSA. Which brings me too...
... HBWR and MGS. Never had morning glories but I love HBWR - one of the most fun and euphoric trips going, in my book. Never had so much as a hint of nausea or bodyload either as long as I make sure to scrape all the fuzzy crap of the outside before chewing 'em. Great stuff and potent as hell if you get decent ones and don't get the nausea and stuff.
Many of the "trippy" capsules have LSA as the main active ingredient so are often pretty similar but more convenient for some. I seem to recall "Purple Ohms" as being the best of the bunch - genuinely very similar to a decent mushroom trip. Only problem was the capsules are a horrid synthetic grape flavour and repeated on me all night. Ick. Would rather chew seeds than keep getting blowbacks from that evil "grape" flavour
There are loads of shitty pills and capsules out there too so can be a bit of a minefield, to be honest. The best ones really are surprisingly good though - if also massively overpriced too.
Also second the mescaline and DMT extractions mentioned above. The extraction bit itself may not be quite legal but buying and possessing all the required ingredients is perfectly legal. Just a terrible shame if they all got knocked over and somehow managed to inadvertently produce some of the finest psychedelic drugs known to man. Doh! Butterfinger 8)
There also always Salvia which some love and some loathe - I'd go for an oral tincture if you can cos it's way nicer than smoking the extracts, in my opinion. As for RCs and stuff... there are a few legal ones - aMT leaps to mind and it's popping up all over the UK on "those" sites at the moment handily enough
PS: Yopo seeds (if you want to discover just how much pain a nostril can take) and a whole host other botanicals are all also perfectly legal so worth looking into too -
