LSA is a very spiritual substance (which like THC, can become too introspective in higher doses).
You can also chew them sublingually, without swallowing, and still get an effect, while avoiding all nausea.
The only thing is, you have to be a determined chewer to get anywhere (someone who chews hundreds of
seeds for over an hour) and the effects are weaker per seed, so you have to chew more seeds.
You could start by chewing 700 heavenly blue seeds, in two batches, over about an hour. This number (350 in each batch) will fill your mouth, so you will look a bit funny while you're chewing them.
The effects will start to kick in after two hours, and will be equivalent to a couple of joints.
Alternatively, if you made a cold water extraction of the same number of seeds (700 seeds), the effects would be a lot stronger, but you might feel some nausea in the first 1-2 hours.
