The concentrations of polonium Po and radio-lead Pb in cannabis (Cannabis sativa L.) plants and products now legally available in Poland were determined. Limiting the delivery of radionuclides to the body is an important aspect of civil protection in many countries. Reduction in use and awareness of the risks associated with tobacco and cannabis smoking have a great impact. The Po and Pb concentrations in 44 hemps, 20 hashish and 8 hemp tea samples, as well as in 3 types of cannabis plants (highest parts of mature hemp plant Fenola, Fedora and Futura) were determined. Each of the sample names means a different type and cross of C. sativa L. Being numerous, the are recognized on the market precisely by these names. Effective doses were calculated and compared to the doses of the other combustion products, such as tobacco. In the case of hemp, the highest concentration of Po was found in samples of dried Sweet Carmel (34.7 ± 0.23 mBq·g), while the lowest in the Hemp Berry (0.57 ± 0.23 mBq·g). In the case of Pb, the highest concentration was in Strawberry Kush (2.32 ± 0.05 mBq·g), while the lowest in Strawberry Haze (0.19 ± 0.03 mBq·g). In hashish, the highest and lowest concentrations of Po were in Strawberry Diesel 164 ± 3 mBq·g and in Mango Kush 2.5 ± 0.2 mBq·g. The highest and lowest concentrations in the case of Pb in hashish were in Pollen Hashish 45.1 ± 0.2 mBq·g and in Mango Kush Hashish 0.45 ± 0.05 mBq·g, respectively. These radionuclides did not constitute a radioactive equilibrium (Po/Pb).
测定了波兰目前合法供应的大麻（Cannabis sativa L.）植物和产品中钋（Po）和放射性铅（Pb）的浓度。限制放射性核素向体内的输送是许多国家民防的一个重要方面。减少与烟草和大麻吸烟相关的风险的使用和认识具有重大影响。测定了 44 种大麻、20 种大麻膏和 8 种大麻茶样品以及 3 种大麻植物（成熟大麻植物 Fenola、Fedora 和 Futura 的最高部位）中 Po 和 Pb 的浓度。每个样本名称都表示不同类型和杂交的 C. sativa L。由于数量众多，这些名称在市场上正是通过这些名称来识别的。计算了有效剂量，并与其他燃烧产物（如烟草）的剂量进行了比较。就大麻而言，在干燥的 Sweet Carmel 样本中发现了最高浓度的 Po（34.7 ± 0.23 mBq·g），而在 Hemp Berry 样本中发现了最低浓度（0.57 ± 0.23 mBq·g）。对于 Pb，最高浓度出现在 Strawberry Kush 中（2.32 ± 0.05 mBq·g），而最低浓度出现在 Strawberry Haze 中（0.19 ± 0.03 mBq·g）。在大麻膏中，Po 浓度最高和最低的分别是 Strawberry Diesel 164 ± 3 mBq·g 和 Mango Kush 2.5 ± 0.2 mBq·g。Pb 浓度最高和最低的分别是 Pollen Hashish 45.1 ± 0.2 mBq·g 和 Mango Kush Hashish 0.45 ± 0.05 mBq·g。这些放射性核素未构成放射性平衡（Po/Pb）。
