Hybrid - 50% Sativa /50% IndicaTHC levels are high in this tropical sativa, topping 24% in some tests. That makes for a potent head high with energizing effects. Euphoria is strong, along with happiness. Critical Neville Haze is a useful medical tool in treating anxiety, depression, and general life stress. The indica genes may also provide some physical pain relief. It's not clear exactly what percentage of this strain is sativa, but the indica genes are definitely in the minority. This strain has a woody taste and aroma with coffee flavoring. Negative effects aren't entirely clear, but they likely include cottonmouth and red eyes. Don't look to Critical Neville Haze for CBD; those levels are very low, making this a less-than-ideal treatment for conditions that respond to that chemical. This strain is a cross between Neville Haze, a sativa-dominant hybrid, and Critical Bilbo, an indica-dominant hybrid. Despite its illustrious heritage, Critical Neville Haze is not a particularly popular strain. It's probably easiest to buy on medical markets in the American West or in Europe, but details of its availability are very hard to come by.
