Some extravagant experiences are Dabs on Dabs on Dabs, or Combined Concentrates.
For the most part, I'm not all that experienced with concentrates, having only been dabbing for a short duration, and there's quite a bit to still try. However, I've had several separate sessions of dabbing and have an expansive repertoire already. Part of that is combining concentrates to significant extremes. It was also very fun. The primary smoking device was Hellboy, a great little rig with a Quartz Castle nail.
Next, we got a little silly and had some of the super-consistent and incredibly tangerine Ghost Train Ecto that was rolled in all-Sativa kief. This was ridiculous - about 10mm wide. The kief added a seriously sharp edge to this delicious Ecto, making it much less tangerine in the aftertaste and much more lemony. It was still super tangerine on the inhale and exhale, like the Ecto is. The high on this massive concentration of Sativa was insane, and talkative as hell. Dabbing this got us up out of our seats and gesticulating.
There was another session where we decided to triple up the dabs. For reference, there is 20mm or so of dabber in the picture, compare it to the JOB rolling paper background. This was just a ridiculous dab, and two people took these. In the bottom of this is some Oakland Kryptonite and it's boogery texture. On the top (background) is delicious White Widow which has caramel texture. In the center, that white crystally thing is the amazing, sharp-edged and sharp-smoking One Love in the Raw. This was tough to get down, being so huge and so many potent marijuanas. But we did it. The high was euphoric as can be, and I went on a journey through several universes. Once I settled back in what I'm fairly certain is Universe Prime, the night continued.
The most lavish and exorbitant of all the dabs was this a massive blob of Ghost Train Ecto wax rolled in the most delectable Phat Albert wax. In case you did not follow any of the links in this post, the Ghost Train Ecto comes in at 74.74% cannabinoids. Phat Albert is 94%. The dab on this was heavenly, if a bit massive. There was serious tangerine flavor as expected - but the Phat Albert tempered it down and made things more lemon, in a similar way but much less intense than the kief did on the other such dab. The high was very intense, a rollercoaster ride for the first 5 or 10 minutes, followed by almost giddy joy and elation. This was incredibly happy and giggly.
