Can you smoke hemp

The short answer is yes. Though be aware that while hemp does have trace amounts of intoxicating compounds, that doesn't mean it will get you high. Hemp plants don't produce enough THC to have an intoxicating effect. CBD, though technically psychoactive, is a non-intoxicating cannabinoid and won't produce any form of a euphoric high on its own.
But if the goal isn't to get an intoxicating high, smoking organic hemp can be an enjoyable and efficient way to experience other cannabinoids like CBD. It's also never been easier to experiment now that you can find organic hemp flowers and pre-rolls online. And while hemp-derived CBD gummies and CBD oil might be all the rage, smoking hemp allows you to self-titrate in real-time — no waiting around for any subtle effects to kick in. 
There's the added bonus of increased bioavailability. Through the act of inhalation, your bloodstream absorbs CBD much faster than it would after eating an edible or using a tincture under your tongue. Your body will also have access to a lot more of the CBD in the smoke or vapor when it's inhaled. When consumed, a CBD edible goes through the digestive tract, and some of the potency is lost in the process. 
For a cleaner burn, consider lighting your hemp flower with a hemp wick. Raw hemp wick coated in beeswax offers a slow burn from all-natural materials, which many users say produces a cleaner cannabis flavor than a lighter or match. The more you know.
