The leaves on the left are a young maple or sycamore (Acer sp.), with a sow thistle (Sonchus sp.) poking out of the middle. I've drunk raw Solanum nigrum plant juice after misidentifying before its flowering time. There were no noticeable psychoactive effects for me, instead it really helped clear up a nasty skin problem for a while. However, my girlfriend felt really dizzy and had to lie down for the remainder of the day - a stark illustration of the different ways that a plant can affect different people.

I've subsequently used a homeopathic preparation of a close relative of this plant (dulcamara) to clear up a chronic skin condition in the long term.

Do you have any more specific information about the effects of solanum spp.? There's a large psychological element to some chronic skin conditions, as recently discussed in another thread.
