计算食用中的THC剂量:完整的数学指南
精确的剂量将专业品质的食物与猜测分开。 本指南提供了计算任何自制大麻产品中精确 THC 含量的公式、示例和工具。
快速回答
使用:(大麻克数)x(十进制百分比)x 1000 x(提取效率)÷(份量) = 每份份的毫克 thc。 示例:10g,在 20% THC 下,效率为 80%,使 20 个巧克力蛋糕 = (10 x 0.20 x 1000 x 0.80) ÷ 20 = 80mg 每个布朗尼。
主公式
完整计算
总 THC (mg) = 大麻重量 (g) x thc 百分比 x 1000 x 提取效率
每份 = 总 THC ÷ 份数
分解它
大麻重量: 使用总克数
百分比:实验室测试百分比或估计值(典型值为 15-20%)
1000: 将克转换为毫克
提取效率:THC 转移到您的输液量(通常为 0.7-0.9)
循序渐进的例子
Scenario
Making 巴布特尔 with 7 grams of 22% THC cannabis, then baking 24 cookies.
步骤一:计算总 THC
7克x 0.22 x 1000 = 1,540毫克THC生大麻
第二步:应用提取效率
对于炉灶黄油输注,估计效率为 75%:
1,540 x 0.75 = 1,155 mg THC 成品黄油
第三步:计算每块饼干的剂量
食谱用1/2杯黄油(一半批次):
1,155 ÷ 2 = 577.5 毫克 THC 在饼干配方中
577.5 ÷ 24 饼干 = 每饼干 24 毫克 THC
提取效率参考
脂肪基输液
酒精酊剂
影响效率的因素
- 温度:最优范围最大化提取
- Time: 更长 = 更多提取(到一个点)
- Agitation:搅拌可改善接触
- 大麻研磨: 中磨是理想的
- 脂肪饱和度:高饱和脂肪结合得更好
向后工作:目标剂量计算
如果您想要每份的特定剂量
需要大麻 = (目标剂量 x 份量) ÷ (THC% x 1000 x 效率)
示例:想要 10mg 饼干,制作 24 个
目标:10mg x 24 = 240mg 总 THC 所需
使用 20% THC 大麻,效率为 80%:
240 ÷ (0.20 x 1000 x 0.80) = 240 ÷ 160 = 1.5 克大麻
调整现有配方
使食谱更强大
Option 1: 用更多的大麻输液
Option 2:在食谱中使用更多的输液(如果食谱允许)
Option 3:少量,较大的部分
使食谱更弱
Option 1:与普通脂肪混合输注(50/50 = 半效力)
Option 2: 做更多,更小的部分
Option 3:最初使用更少的大麻
未知的四氢大麻酚百分比
当你不知道效力时
基于质量的估计:
- 低质量/装饰: 8-12% THC
- 普通花: 15-18% THC
- 品质花: 18-22% THC
- 溢价花: 22-28% THC
- 浓缩:60-90% THC
保守的方法
不确定时,使用更高的估计值(20%)。 这假设大麻更强,并导致剂量更低 - 比低估更安全。
集中计算
馏分油和油
浓缩物通常为 60-90% THC。
Example:1克80% THC馏分
1 x 0.80 x 1000 = 800 毫克 THC
直接添加到配方中时不会损失提取效率。
蜡/碎石
Slightly lower (60-80% typically). Decarb before using if not already activated.

- A1:大麻克(10)
- A2:THC百分比(0.20)
- A3:效率(0.80)
- A4:份量 (24)
- A5:公式:=(A1A21000A3)/A4
Result: 66.67 mg per serving
Common Scenarios Calculated
Scenario 1: Standard Brownie Batch
- 14g (1/2 oz) cannabis at 18% THC
- Stovetop butter infusion (75% efficiency)
- 16 brownies
Calculation: 14 x 0.18 x 1000 x 0.75 ÷ 16 = 118 mg per brownie
This is very strong. Cut into 32 pieces for ~59mg each.
Scenario 2: Mild Cookies
- 3.5g (1/8 oz) cannabis at 20% THC
- Slow cooker oil (80% efficiency)
- 24 cookies
Calculation: 3.5 x 0.20 x 1000 x 0.80 ÷ 24 = 23 mg per cookie
More reasonable dose.
Scenario 3: Micro-Dose Gummies
- Tincture containing 500mg THC total
- Making 50 gummies
Calculation: 500 ÷ 50 = 10 mg per gummy
Standard commercial-equivalent dose.
Accounting for Cooking Losses
Additional THC Degradation
Some THC degrades during cooking. Additional 10-20% loss is possible at high temperatures.
Conservative final calculation:
Calculated dose x 0.85 = realistic expectation
Minimizing Cooking Losses
- Bake at 325°F instead of 350°F
- Reduce cook time when possible
- Add infused ingredient near end of cooking when feasible
Testing Your Calculations
The Test Dose Method
Before consuming full serving:
1. Calculate expected dose
2. Consume 1/4 of that amount
3. Wait 2 hours for full effects
4. Evaluate accuracy
5. Adjust calculations if needed
Keeping Records
Log each batch:
- Cannabis amount and source
- Assumed THC percentage
- Infusion method used
- Number of servings made
- Calculated dose per serving
- Actual effects experienced
This data improves future calculations.
