Jesus christ you two are overreacting. It's 5X. You're not going to be flying no matter how much you smoke. At that concentration expect slight vision distortion, loss of motor control, uncontrollable laughter and a rather annoying pins and needles feeling. It's going to be fun, but you will be very well grounded in this world. Get some 30x+ if you really want to fly, though personally I prefer 20x. It fucks you up, but you're still existing in this astral plane, with one foot firmly implanted in sanity.
