Chem #4 BHO (CAM)
Name: Chem #4 BHO (Butane Hash Oil)
Type: Butane extracted hash oil, made from 100% in-house ChemDawg #4 (Sativa-dominant hybrid)
Grade: A- (amongst butane-extracted hash oil samples)
Consumption Method: Essential Vape, glass wand, and TI skillet
Visual: (8.5/10) Though this oil seemed very shiny and like it would be almost wet to the touch, it was actually rather stable and easy to handle, especially when stored in the fridge or freezer, which we’d recommend (it does begin to melt a bit when excessively handled manually). The color was a mustardy golden yellow and it seemed rather opaque, as no bubbles were visible except at the microscope level. As far as those bubbles, it’s unclear if it was simply residual moisture or gas bubbles that weren’t purged from the final product… we didn’t pick up any hints of residual butane in the flavor or smell, but it’s worth mentioning.
Smell: (9/10) This was one of the strongest-smelling butane extracts we’ve encountered — it was very pungent and almost exactly like the parent strain, which is highly appreciated in a strain-specific extract. Chem #4 is known for its acrid pine-fuel-citrus combination aroma, and this extract delivers that in spades, especially on the fingers when handled. Along with the clear Chem influences, there was also the standard lightly vegetal pine tar-like aroma that we’ve come to recognize as essentially the base aroma of cannabis extracts.
Flavor: (8.5/10) The flavor was much like the smell, hitting all the proper notes for a Chem strain, with strong flavors of lemon pinesol and fuel. The majority of the review staff coughed rather heavily almost immediately after exhaling, and that continued for a few minutes. One reviewer using a titanium skillet experienced no real harshness, but it gave that constrictive chest feeling that made it tough to breathe for a minute or two, then it cleared up immediately after, making us almost feel as if our lungs and throat were more clear than they started.
Consumption: This extract disappeared almost immediately when placed on the skillet or wand, and left only a particulate-free amber-colored film on the Essential Vape vial, indicating the absence of plant matter and other physical contaminants. On the skillet when applied via metal implement slowly, there was a bit of sizzling, but the extract disappeared so quickly that it was hard to notice. The coughing is something that we’ve learned mostly comes with the territory of extracts, and this one was no exception, though it was almost entirely the constrictive chest type of feeling rather than outright harshness on the throat itself. Like most extracts, this one isn’t meant for novice patients who cannot handle coughing or strong early effects.
Effects/Duration: Coughing definitely played a role in the early effects, as we all felt immediate rushes of heat and pressure to the head and eyes, but those effects stayed strong after the coughing stopped, even increasing in potency over the initial 15 minutes. There was a good amount of perspiration from some of the staff, but we all got a strongly fluttery feeling in the chest and a boost in mental activity, almost to a frenzied state. While the mind was busy (perhaps overly-so, making single-track focus a bit difficult), the body was mostly immobile, leaving the user to sit and digest (or enjoy, really) the seemingly expanded senses and psychoactivity that ensued over the first hour. Beyond that extremely potent first hour, the effects stayed strong but changed in the sense that it mostly served to enhance rather than directly affect most senses and mental faculties. We seemed to notice a lot of fluctuations in potency throughout this experience — it never seemed to stay the same for more than 30 minutes, and at times we’d find ourselves staring blankly into space, and at times working busily and not thinking about the effects. A slow dwindle over approximately 4 hours came with no real lingering effects or downsides — we didn’t “crash” and the rest of the day had us feeling normal.
Overall: This Chem #4 BHO was as pungent-smelling a butane extract as we’ve ever encountered, and one reviewer said the initial effects were as medicated as he can remember being — so there’s certainly a lot to like about this one. While the tiny bubbles visible in the pictures above did make us slightly nervous, we didn’t really see, taste, or smell and other evidence of residual butane. Like most extracts, this one is not or beginners, both due to its potency level, and also due to its tendency to cause some fairly heavy coughing. However, once the initial hash sweat + heavy cranial pressure phase died off, we felt very stimulated mentally, in a capable yet semi-distracted way, our focus running to a variety of things. The lack of a directly tiring comedown or lingering effects was a bonus for such a strongly Sativa-feeling med, as was the rather long duration, with medicinal effects staying fairly constant through 2.5 hours, trailing out over 4+ total. We like this one as a daytime med primarily, though the strong eye effects might cause a late-night session to turn into an unexpected nap on the couch.
